Successful exploitation of these vulnerabilities could result in an attacker accessing sensitive credentials, disrupting connected infrastructure, or manipulating physical equipment, which could present a physical safety risk.
\nThe following versions of Tycon Systems TPDIN-Monitor-WEB2 (Update A) are affected:
\n| CVSS | \nVendor | \nEquipment | \nVulnerabilities | \n
|---|---|---|---|
| v3 9.8 | \nTycon Systems | \nTycon Systems TPDIN-Monitor-WEB2 | \nMissing Authentication for Critical Function, Cleartext Storage of Sensitive Information | \n
The device ships without HTTP credentials configured, intended for an installer to set them on first use. On firmware 2.4.4 and earlier, a unit left in this unconfigured state serves the web management interface without requiring any login. An attacker with network access to such a unit can reach full device controls, including power relay management, device reboot, remote access service configuration, and network settings, which could allow disruption of connected infrastructure or physical damage to equipment.
\n\nVendor fix
Tycon Systems has released firmware 2.4.5, which resolves this vulnerability by requiring an administrator username and password to be set before the web interface is served. Further inquiries can be directed to security@tyconsystems.com.
Mitigation
Tycon Systems recommends setting an administrative username and strong password on the Network Configuration page and confirming in a private browser window that a login is required, for units still running firmware 2.4.4 or earlier. Repeat this after any factory reset.
Mitigation
Tycon Systems recommends not exposing the web interface to the Internet, as it is HTTP only. The unit should be kept on a private network, behind a firewall or VPN.

The device's web management interface stores and displays system credentials in cleartext on a certain configuration page accessible to authenticated users. Any party with access to the administrative dashboard can immediately read these credentials, which may be used to compromise other systems on the local network.
\n\nVendor fix
Tycon Systems has released firmware 2.4.5, which resolves this vulnerability by removing cleartext credentials from the web interface response. Further inquiries can be directed to security@tyconsystems.com.
Mitigation
Tycon Systems recommends changing any factory-default SNMP community strings and the Telnet password if they were left at shipped values. Leave Telnet disabled unless required.
Mitigation
Tycon Systems recommends using a dedicated mail account for device alerts, rather than an account also used for other sensitive purposes, to limit exposure if credentials are compromised.

Successful exploitation of this vulnerability could allow any authenticated user to create projects.
\nThe following versions of Inductive Automation Ignition are affected:
\n| CVSS | \nVendor | \nEquipment | \nVulnerabilities | \n
|---|---|---|---|
| v3 8.8 | \nInductive Automation | \nInductive Automation Ignition | \nIncorrect Default Permissions | \n
In Ignition 8.1.53 and earlier, the Gateway \"Create Project Role(s)\" setting shipped blank, which permitted any authenticated user to create projects (if they can execute gateway scripts). Ignition 8.1.54 restricts project creation to Designer sessions and no longer relies on this setting. The 8.3 series is not affected.
\n\nMitigation
Inductive Automation has determined that this issue is a default-value configuration, not a flaw in the access control itself. The security control enforces exactly what the \"Create Project Role(s)\" setting specifies; because the setting shipped blank, no role was required to create a project. Populating the setting fully closes the vulnerability.
Mitigation
Inductive Automation recommends users upgrade to 8.1.54 or later (or the latest 8.3 version), which restricts project creation to Designer sessions and no longer relies on this setting. Users who must remain on an earlier 8.1 version can fully remediate the issue by setting \"Create Project Role(s)\" to match their Designer Role. Once the setting is populated, only users holding that role can create projects. See Gateway General Security Settings.

We strongly recommend the following industry cybersecurity best practices. * Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. * Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. * Place all controllers in locked cabinets and never leave them in the \u201cProgram\u201d mode. * Never connect programming software to any network other than the network intended for that device. * Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. * Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. * Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

Successful exploitation of this vulnerability could allow an attacker to perform remote code execution on the computer running the client with elevated privileges.
\nThe following versions of IXON VPN Client are affected:
\n| CVSS | \nVendor | \nEquipment | \nVulnerabilities | \n
|---|---|---|---|
| v3 9.6 | \nIXON | \nIXON VPN Client | \nImproper Neutralization of CRLF Sequences ('CRLF Injection') | \n
Improper Neutralization of CRLF Sequences (CWE-93) in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralised, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester (CWE-306, contributing). The injected configuration persists on disk across restarts of the client and the operating system, and the VPN connection continues to function normally, so there is no behavioral change visible to the user.
\n\nMitigation
IXON recommends updating the IXON VPN client to version 1.4.7 or later on every computer where it is installed.
Mitigation
As of August 5, 2026, IXON cloud rejects connections from clients below v1.4.7 at both the portal and the back-end API. Since the privileged subprocess and injected listener are only created when the client connects, unpatched installations cannot complete the exploit chain.
Mitigation
If the client is no longer needed, IXON recommends uninstalling the VPN client from the computer.

CISA and the Group of Seven (G7) Cyber Security Working Group released Preparing for the Post-Quantum Era: A Call to Action highlighting the urgent need for organizations and governments to begin transitioning to post-quantum cryptography (PQC) to protect sensitive data, authentication systems, and critical assets from emerging quantum computing threats.
\nThe G7 Cyber Security Working Group\u2019s call to action outlines five priorities for a successful transition to PQC:
\nSuccessful exploitation of this vulnerability could result in memory corruption, a device crash, or a potential remote attack vector without the originating device receiving a CIP error indicating that the request could not be processed.
\nThe following versions of Pyramid Solutions NetStaX EtherNet/IP Stack are affected:

|---|---|---|---|
| v3 9.8 | \nPyramid Solutions | \nPyramid Solutions NetStaX EtherNet/IP Stack | \nStack-based Buffer Overflow | \n
An issue in the NetStaX EtherNet/IP Stack prior to v5.6.1 could allow a large Class 3 explicit-message request to exceed the application-side receive buffer without generating an error or warning. The result could be memory corruption, a device crash, or a potential remote attack vector without the originating device receiving a CIP error indicating that the request could not be processed.

CISA has added seven new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
\nThese types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.
\nBinding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA\u2019s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied.
\nWhile BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
\nAware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA\u2019s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
\nDeveloped by CISA, the Federal Bureau of Investigation, and international partners, this guidance describes how organizations can plan and execute clear, timely, accurate, and audience-appropriate communications during IT and operational technology (OT) outages. Whether caused by cyber threat actors, human error, equipment failure, or natural hazards, service outages can create disruption and societal panic even without speculation from end users and the public as added factors. Outages at one organization may cascade across interconnected systems, increasing uncertainty and alarm. The guidance emphasizes clarity, accountability, and transparency as core principles and details key elements of effective crisis messaging to inform affected stakeholders and the public while aligning with legal requirements, operational security, law enforcement, and containment efforts.
\nCISA\u2019s CI Fortify initiative provides information and resources that help critical infrastructure organizations prepare to isolate and recover vital OT systems during a major cyber incident or crisis. Changes in service availability, whether from outages or isolation as a defensive strategy, require transparent and ongoing communication to help end users minimize operational impact, limit speculation, and preserve trust. For emergency planning purposes, critical infrastructure owners and operators should assume that telecommunications services may be disrupted or otherwise unreliable, making it crucial for organizations to have crisis communications plans in place that integrate backup communication methods and understand the type of communication they should expect from their service providers.

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
\nThese types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.
\nBinding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA\u2019s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied.
\nWhile BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
\nAware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA\u2019s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
\nSuccessful exploitation of this vulnerability could allow a remote attacker to cause a denial-of-service (DoS) condition, a timeout error, or a communication delay by sending a specially crafted UDP packet to the product.

\nCISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
\nMinimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
\nLocate control system networks and remote devices behind firewalls and isolating them from business networks.
\nWhen 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 current version available. Also recognize VPN is only as secure as the connected devices.
\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
\nCISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
\nCISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
\nAdditional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
\nOrganizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
\nThese vulnerabilities have a high attack complexity.

CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
\nThese types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.
\nBinding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA\u2019s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied.
\nWhile BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
\nAware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA\u2019s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.

Cyber threat actors scan the internet looking for exposed, well-known software vulnerabilities to exploit. Basic security failures enable most compromises and organizations can reduce their risk by addressing these underlying weaknesses and prioritizing vulnerabilities for action based on the risk they pose.
\nThe CISA Vulnerability Review provides organizations with critical insights into the root causes of insecure software and practical steps they can take to address these flaws to prevent exploitation. Analyzing CISA and open source data from fiscal years 2024 and 2025, the review establishes a baseline of today\u2019s vulnerability landscape before AI-enabled vulnerability discovery becomes more widespread. The review demonstrates the importance of Secure by Design principles in shifting cybersecurity efforts from reacting to threat actors to proactively fixing preventable software flaws.
\nThe review also identifies common software weaknesses that contribute to exploitable vulnerabilities and details practices software producers can use to prevent these weaknesses from recurring. By examining the patterns across vulnerability data, the review helps organizations focus on systemic improvements that can reduce entire classes of vulnerabilities rather than addressing individual vulnerabilities only after they are discovered.
\nAdditionally, the review shows organizations how to prioritize vulnerabilities for action using the framework outlined in Binding Operational Directive 26-04: Prioritizing Security Based on Risk. This framework evaluates vulnerabilities using four key criteria: exposure status, Known Exploited Vulnerability (KEV) Catalog status, potential for automated exploitation, and technical impact.
