CISA and Partners Urge Hardening Automatic Tank Gauge Systems
\nThe Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the National Security Agency (NSA), the Department of Energy (DOE), the Environmental Protection Agency (EPA), the Transportation Security Administration (TSA), the Department of Transportation (DOT), and the U.S. Department of Agriculture (USDA)\u2014hereafter referred to as \u201cthe authoring organizations\u201d\u2014are aware of malicious cyber activity targeting U.S.-based automatic tank gauge (ATG) systems. ATG systems are widely used throughout the Energy, Chemical, Food and Agriculture, and Transportation Systems Sectors for automated and remote monitoring of storage tank parameters, including fuel and liquid levels, temperature, and possible leak detection. The authoring organizations urge ATG owners and operators to defend against this malicious activity by securing their ATG systems with strong passwords and by removing them from the internet to reduce public exposure.
\nThe recent malicious cyber activity observed by the authoring organizations\u2014which the U.S. government has not yet attributed to a nation-state or threat actor group\u2014involves cyber threat actors compromising internet-exposed ATG systems and subsequently modifying them through command execution. This fact sheet provides insight into probable tactics, techniques, and procedures (TTPs) leveraged by these cyber actors, highlights risk factors associated with such compromises, and provides mitigation guidance and resources to reduce the likelihood of continued malicious activity targeting U.S.-based ATG systems.
\nCyber threat actors may exploit flaws in ATG systems through multiple attack vectors:
\nShould a cyber threat actor exploit these vulnerabilities and compromise an ATG system, they could disrupt or manipulate the below critical functions by interfacing directly with the tank management as though they possessed legitimate physical access to the system console. The cyber threat actors could:
\nThe authoring organizations recommend ATG owners immediately implement the following recommendations:
\nThe authoring organizations recommend ATG owners and operators review the following resources and implement suggested mitigations, where possible, to enhance their security posture.
\nThe authoring organizations recommend U.S. organizations report suspicious or criminal activity related to information provided in this fact sheet.

CISA is prioritizing the response to multiple emerging software supply chain intrusion campaigns targeting developer ecosystems Continuous Integration/Continuous Development (CI/CD) pipelines. These recent incidents, including the GitHub compromise via a malicious Nx Console Visual Studio Code (VS Code) extension and the \u201cMegalodon\u201d supply chain intrusion campaign, demonstrate how cyber threat actors are abusing tools and processes that support enterprise, cloud, and DevOps environments\u2014specifically CI/CD pipelines, code extensions and workflows.
\nThreat actors leveraged a prior compromise of Nx developer systems to compromise a GitHub employee\u2019s device through a poisoned third-party VS Code extension, resulting in unauthorized access and exfiltration of internal GitHub repositories. The malicious extension version (18.95.0) was distributed through VS Code\u2019s automatic update mechanism, meaning systems with Nx Console previously installed may have received the malicious build without developers taking any manual installation action. GitHub released a security advisory on this activity, and CVE-2026-48027 has been assigned to the malicious version of Nx Console and added to CISA\u2019s Known Exploited Vulnerabilities (KEV) Catalog.
\nAdditionally, in a campaign known as \u201cMegalodon,\u201d a cyber threat actor injected malicious GitHub Action workflows to harvest CI/CD secrets, cloud credentials, and tokens, impacting both development and deployment pipelines in public GitHub repositories.
\nCISA urges organizations to implement the following recommendations to detect and remediate a potential compromise:
\nbuild-bot, auto-ci, ci-bot, pipeline-bot and especially those made after May 18, 2026.If your organization discovers a compromise resulting from previously compromised GitHub or Nx Console software, CISA recommends the following steps:
\nCISA recommends the following best practices for using package repos:

\nWhat causes the vulnerability? The vulnerability is caused by code defect allowing the attacker to extract the sensitive information such as user credentials from memory dump of the application. Please refer to Vulnerability severity and details for further details. What is MConfig ? MConfig is the parameterizing software for ABB LV switchgear components such as motor and feeder controller, operation panel, temperature monitoring solutions and protocol converter. The components are physically installed in a low voltage switchgear located in switch rooms that require authority to access. To run this software on a host machine (computer), the operating system should be Win11 or later version. What might an attacker use the vulnerability to do? If the mentioned vulnerability has been successfully exploited by an attacker, this could allow the attacker to extract sensitive information such as user credentials. With user credentials and access to a host machine with MConfig installed, and access to the switch room with components installed in a switchgear, the attacker can modify the setting of the components potentially compromising its correct operation. How could an attacker exploit vulnerability? An attacker with host machine physical access could, after a user log into MConfig, exploit a vulnerability by exporting a memory dump during runtime, potentially exposing the user's password. Could vulnerability be exploited remotely? The vulnerability can only be exploited if an attacker has physical access to the host machine with MConfig software. What does the update do? MConfig version V1.4.9.22 update has fix for the vulnerability mentioned in Vulnerability severity and details section. The measures below were implemented to fix the vulnerability: \u2022 Clear any authentication-related memory data after a successful login. \u2022 Hash the passwords in SHA256

ABB is aware of public reports of vulnerabilities in a 3rd party component VLC media player Version 2.2.4 which was delivered together with the installation package of Camera Connect Version 1.5.0.14 and below. An update is available that resolves a privately reported outdated 3rd party component with vulnerabilities in the product versions listed as affected in this advisory. An attacker who successfully exploited any of these vulnerabilities in the 3rd party component could potentially compromise the system in different ways.
\nThe following versions of ABB Ability Camera Connect are affected:
\n| CVSS | \nVendor | \nEquipment | \nVulnerabilities | \n
|---|---|---|---|
| v3 9.8 | \nABB | \nABB Ability Camera Connect | \nHeap-based Buffer Overflow, Integer Underflow (Wrap or Wraparound), Out-of-bounds Write, Uncontrolled Search Path Element, Integer Overflow or Wraparound, Off-by-one Error, Out-of-bounds Read, Double Free, Improper Restriction of Operations within the Bounds of a Memory Buffer, Use After Free | \n
VLC media player 3.0.20 and earlier is vulnerable to denial of service through an integer overflow which could be triggered with a maliciously crafted mms stream (heap based overflow). If successful, a malicious third party could trigger either a crash of VLC or an arbitrary code execution with the target user's privileges.
\n\nMitigation
The VLC-based component operates solely within completely isolated environments without internet access or any connectivity to external networks. Consequently: \u2022 No exposure to untrusted MMS streams: The integer overflow vulnerability relies on handling a maliciously crafted external stream, which is not possible in isolated environments \u2022 No remote attacker access: Without network ingress, attackers cannot trigger the vulnerability remotely. \u2022 Drastically reduced attack surface: The absence of any external media inputs effectively neutralizes the exploit path, significantly lowering the risk of both denial of service and code execution.
Vendor fix
The problem is corrected in the following product versions: ABB Ability Camera Connect 1.5.0.15 The 3rd party component has already been updated. The easiest path to mitigate the problem is an update of just VLC Media Player by the customer. ABB recommends that customers apply the update at earliest convenience. It is also possible to update to the latest Version of Camera Connect.
Relevant CWE: CWE-122 Heap-based Buffer Overflow
\n| CVSS Version | \nBase Score | \nBase Severity | \nVector String | \n

Videolan VLC prior to version 3.0.20 contains an Integer underflow that leads to an incorrect packet length.
\n\nMitigation
\u2022 Air-gapped environments only: Camera Connect is deployed in completely isolated environments lacking any network connectivity or internet access. \u2022 No exposure to MMS streams: The vulnerability depends on processing crafted MMS streams, which cannot originate from external or internal network sources when the system is air-gapped. \u2022 Elimination of remote attack surface: Without any method for an attacker to deliver malicious media inputs, the vulnerability cannot be triggered remotely. \u2022 Strong reduction in exploitation risk: The combined absence of external media ingestion and unavailable network paths effectively neutralizes the integer underflow exploit, significantly reducing the likelihood of both denial-of-service and memory corruption scenarios.

Videolan VLC prior to version 3.0.20 contains an incorrect offset read that leads to a Heap-Based Buffer Overflow in function GetPacket() and results in a memory corruption.
\n\nMitigation
Given that Camera Connect is deployed exclusively in fully isolated, air-gapped environments with no internet access or external network connectivity, the following risk-reduction factors apply: \u2022 No exposure to crafted MMS streams: The exploit requires the receipt of specially crafted packets via the MMS protocol, which cannot occur without network connectivity. \u2022 Network attack vector eliminated: As the vulnerability\u2019s CVSS vector highlights a network-based attack (AV:N), the lack of any ingress network path nullifies the attack surface. \u2022 Low likelihood of exploitation: Without access to malicious media input, there is effectively no practical method for an attacker to trigger memory corruption, making the likelihood of denial of service or arbitrary code execution negligible.

A binary hijacking vulnerability exists within the VideoLAN VLC media player before 3.0.19 on Windows. The uninstaller attempts to execute code with elevated privileges out of a standard user writable location. Standard users may use this to gain arbitrary code execution as SYSTEM.
\n\nMitigation
Given that the VLC-based component is installed exclusively within air-gapped environments under strict administrative control, the following factors substantially reduce risk: \u2022 Restricted user access: Only trusted, privileged users perform installations and modifications. Standard users have no write permissions to the uninstaller directory. \u2022 No internet or network access: The exploit requires local manipulation of VLC\u2019s uninstaller files; without external connectivity, remote coercion or manipulation is impossible. \u2022 Elimination of attacker vector: In air gapped deployments with administrative controls, un-privileged users cannot place malicious DLLs or executables in the uninstaller\u2019s search path. \u2022 Minimized privilege escalation risk: The combination of controlled write access, absence of network exposure, and trusted user roles effectively neutralizes the binary hijacking threat, rendering successful exploitation highly unlikely.

Since the system only processes trusted media files\u2014validated through internal procedures and se-cured media channels\u2014the probability of exposure to hostile MP4 content is minimal. Therefore, the risk of successful exploitation is significantly mitigated by the restricted deployment context.
Vendor fix
The problem is corrected in the following product versions: ABB Ability Camera Connect 1.5.0.15 The 3rd party component has already been updated. The easiest path to mitigate the problem is an update of just VLC Media Player by the customer. ABB recommends that customers apply the update at earliest convenience. It is also possible to update to the latest Version of Camera Connect.

plugins\\audio_filter\\libmpgatofixed32_plugin.dll in VideoLAN VLC media player 2.2.4 allows remote attackers to cause a denial of service (invalid read and application crash) or possibly have unspecified other impact via a crafted file.
\n\nMitigation
This vulnerability affects the libmpgatofixed32_plugin.dll module in VLC 2.2.4, which is responsible for decoding MPEG audio streams. The software in question does not process audio files or use any functionality related to audio decoding, meaning the vulnerable component is never invoked during normal operation. Additionally, the deployment environment is fully offline with no internet connectivity, and media ingestion is restricted to trusted internal sources. As a result, the attack surface for this vulnerability is effectively nonexistent, and the risk of exploitation is negligible under these conditions.

\nTo attack with this kind of message, hackers must hijack CSMS (OCPP backends) first and then can send messages, OR the way to OCPP backend is unsafe itself (http) which can cause any kind of attack behavior and known as a common knowledge. Refer to section \u201cGeneral security recommendations\u201d for further advise on how to keep your system secure.
\nMake sure OCPP backend that chargers are connected is strictly secured to avoid any kind of at-tack especially the communication relevant components. Use https(TLS) as basic communication foundation between charger and OCPP backend instead of http.
\nWhat causes the vulnerability? The vulnerability is caused by firmware which it didn\u2019t limit the length of OCPP field in certain case. What is Terra AC wallbox? Terra AC wallbox is a Level 2 Electric Vehicle charger. What might an attacker use the vulnerability to do? An attacker who successfully exploited this vulnerability could cause the affected system node to take control of the charger to response wrong messages, Denial-of-Service, compromised internal state, and possibly remote code execution. How could an attacker exploit the vulnerability? An attacker could try to exploit the vulnerability by sending a specially crafted OCPP message to chargers via OCPP backend(CSMS), which could be done remotely. This would require that the attacker has access to the system network and hijack the API of sending message OR hijack the network data directly if the charger is connected with unsafe http mode. Recommended practices help mitigate such attacks, see section Mitigating Factors above. Could the vulnerability be exploited remotely? Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Can functional safety be affected by an exploit of this vulnerability? The charger potentially is running with unpredictable mode, including Denial-of-Service, compromised internal state, and possibly remote code execution. What does the update do? The update removes the vulnerability by modifying the validation rules of receiving data from OCPP backend. When this security advisory was issued, had this vulnerability been publicly disclosed? No, ABB received information about this vulnerability through responsible disclosure. When this security advisory was issued, had ABB received any reports that this vulnerability was being exploited? No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued

ABB is aware of vulnerabilities in the product versions listed as affected in the advisory. The vulnerability enables unauthorized access to the Reboot OS function within the Remote Transport Service, allowing an attacker to trigger a system reboot without the required authentication. This functionality initiates a system reboot on the target machine. However, remote exploitation of this vulnerability is not feasible unless the attacker has already gained access to the network where the affected ABB Ability Zenon system is deployed. At the time of writing, there is no evidence that this vulnerability is being actively exploited in the wild.
\nThe following versions of ABB Ability Zenon Remote Transport Vulnerability are affected:
\n| CVSS | \nVendor | \nEquipment | \nVulnerabilities | \n
|---|---|---|---|
| v3 7.5 | \nABB | \nABB Ability Zenon Remote Transport Vulnerability | \nMissing Authentication for Critical Function | \n
In the default configuration of the ABB Zenon software platform, the zensyssrv.exe service is set to start automatically. To utilize the Remote Transport Service, users are required to configure a password beforehand. However, a security vulnerability has been identified that enables unauthorized attackers to bypass authentication mechanisms and remotely initiate a system reboot without proper authorization
\n\nWorkaround
\u2022 Restrict network access to systems with the ABB Zenon Software Platform installed. - Ensure that access to a system is restricted by implementing access controls to minimize the risk of unauthorized access. \u2022 Assess the necessity of the ABB Zenon Remote Transport functionality. - Ensure that if the Remote Transport functionality is not used, the zensyssrv.exe (ABB Zenon System Service) is stopped or terminated. The zensyssrv.exe can also be stopped or terminated after authorized use to prevent this vulnerability.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
\nThis type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise.
\nBinding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.
\nAlthough BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

\nWhat is the scope of the vulnerabilities? - A network attacker who successfully exploited these vulnerabilities to execute remote code, initiate DoS attacks, conduct DNS cache poisoning, or extract sensitive information. In worst case, these vulnerabilities can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability. What causes the vulnerabilities? - The vulnerabilities are caused by usage of vulnerable UEFI firmware in some B&R xPCs. What is a B&R xPC? - A B&R xPC is an industrial PC (IPC) designed for use in industrial environments and is built to handle more demanding conditions than a standard PC. They often feature robust construction, resistance to dust and moisture, extended temperature ranges, and other specifications suited for industrial applications. What might an attacker use the vulnerabilities to do? - A network attacker who successfully exploited the vulnerabilities could execute remote code, initiate DoS attacks, conduct DNS cache poisoning, or extract sensitive information. How could an attacker exploit the vulnerabilities? - An attacker could try to exploit the vulnerabilities by creating a specially crafted message and sending the message to an affected system node. This would require that the attacker has access to the system network, by connecting to the network either directly or through a wrongly configured or penetrated firewall, or that he installs malicious software on a system node or otherwise infects the network with malicious software. Recommended practices help mitigate such attacks, see section Mitigating Factors above. Could the vulnerabilities be exploited remotely? - Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Recommended practices include that process control systems are physically protected, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed. What does the update do? - The update removes the vulnerabilities in the TCP/IP stack used by the UEFI firmware. When this security advisory was issued, had these vulnerabilities been publicly disclosed? - Yes, these vulnerabilities have been publicly disclosed. When this security advisory was issued, had B&R received any reports that this vulnerability was being exploited on B&R products? - No, B&R had not received any information indicating that this vulnerability had been exploited on B&R products when this security advisory was originally issued.

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
\nThese types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.
\nBinding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.
\nAlthough BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

An attacker successfully exploiting this vulnerability could send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection. For immediate mitigation /workaround information, please refer to the General Mitigation Factors/Workarounds

A timing-based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.

\nRecommended security practices and firewall configurations such as enforcing ingress IP allowlisting and applying traffic rate limiting in accordance with the operational security policy can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system.

Hyperlinks may be provided via: \u2022 Emails from unknown users \u2022 Social media channels \u2022 Messaging services \u2022 Webpages with comment functionality \u2022 QR Codes The use of external Web Application Firewalls (WAF) can mitigate attacks using reflected cross-site scripting.
\nWhat causes the vulnerabilities? The vulnerabilities are caused by insufficient input sanitization and generation of predictable numbers. What is System Diagnostics Manager (SDM)? System Diagnostics Manager (SDM) is a webpage available over the Automation Runtime Webserver, showing key diagnostic information of the running controller. What is Automation Runtime (AR)? B&R Automation Runtime is a middleware system enabling customers to run applications on B&R target systems. What might an attacker use the vulnerabilities to do? An attacker who successfully exploited these vulnerabilities could cause to run arbitrary code in the context of the user\u2019s browser session or take over the user\u2019s session. Since the SDM currently does not process any session-specific data and also does not implement authentication mechanisms at the session level, B&R is not aware of any advantages an attacker could gain by taking over the session ID How could an attacker exploit the vulnerabilities? To exploit the XSS vulnerability CVE-2025-3448, an attacker could try to create a hyperlink including malicious script code. This hyperlink must be opened by the user to launch the attack. To exploit vulnerability CVE-2025-3449, an attacker would need to guess a user's session ID. Could the vulnerabilities be exploited remotely? Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Recommended practices include that process control systems are physically protected, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed. When this security advisory was issued, had this vulnerability been publicly disclosed? No, B&R discovered the vulnerabilities through its own security analysis. When this security advisory was issued, had B&R received any reports that this vulnerability was being exploited? No, B&R had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued.
