The following versions of ABB Ability Camera Connect are affected: Ability Camera Connect vers:intdot/<=1.5.0.14, 1.5.0.15 CVSS Vendor Equipment Vulnerabilities v3 9.8 ABB ABB Ability Camera Connect Heap-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 Background Critical Infrastructure Sectors: Chemical, Commercial Facilities, Communications, Critical Manufacturing, Energy, Transportation Systems Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2024-46461 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. View CVE Details Affected Products ABB Ability Camera Connect Vendor: ABB Product Version: ABB Ability Camera Connect <=1.5.0.14 Product Status: fixed, known_affected Remediations Mitigation The VLC-based component operates solely within completely isolated environments without internet access or any connectivity to external networks. Consequently: • 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 • No remote attacker access: Without network ingress, attackers cannot trigger the vulnerability remotely. • 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.

View CVE Details Affected Products ABB Ability Camera Connect Vendor: ABB Product Version: ABB Ability Camera Connect <=1.5.0.14 Product Status: fixed, known_affected Remediations Mitigation Because the affected VLC version (2.2.4) suffers from a heap out of bound read in the ParseJSS function—allowing an attacker to read uninitialized heap data via a crafted subtitles file—the risk of external exploitation is significantly reduced in your environment. Since the software is installed in strictly isolated systems with no internet access, no external attacker can deliver malicious subtitle files re-motely. Consequently, the only remaining exposure is local: an insider would need to intentionally load a crafted subtitle file to trigger the issue—a scenario considered highly unlikely under current governance and usage controls.

All rights to registrations and trademarks reside with their respective owners. Mitigating factors To 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 “General security recommendations” for further advise on how to keep your system secure. Workarounds Make 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. Frequently asked questions What causes the vulnerability? The vulnerability is caused by firmware which it didn’t 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?

View CSAF Summary Hitachi Energy is aware of the vulnerability, CVE-2022-4304 in the OSS component OpenSSL, that affects the GMS600 versions that are listed below. 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 The following versions of Hitachi Energy GMS600 are affected: GMS600 vers:GMS600/>=1.3.0|<=1.3.1 (CVE-2022-4304) CVSS Vendor Equipment Vulnerabilities v3 5.9 Hitachi Energy Hitachi Energy GMS600 Observable Discrepancy Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2022-4304 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.

General Mitigation Factors Recommended 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.

Frequently Asked Questions What 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. Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov.
