CVE-2026-16731 OMICRON electronics GmbH CVE debrief

Who should care

Organizations using OMICRON StationScout versions prior to 3.05 should prioritize verification and remediation efforts due to the potential for authentication bypass and high CVSS score. Affected operators, platforms, and security teams should review system configurations and inventory for OMICRON StationScout versions prior to 3.05 and implement compensating controls to monitor and restrict access to system parameters. Vulnerability management and security teams should conduct regular security audits and vulnerability assessments to identify and remediate potential vulnerabilities. IT and network administrators should review relevant monitoring, detection, and logs for exposed assets that need extra review and track exceptions, retest remediated assets, and close the item only after evidence is documented. Security teams should also consider implementing additional security controls, such as multi-factor authentication and intrusion detection systems, to further protect against potential attacks. Additionally, security teams should review and update their incident response plans to ensure they are prepared to respond to potential security incidents related to this vulnerability. Security awareness training should also be provided to employees to educate them on the potential risks associated with this vulnerability and the importance of reporting any suspicious activity. Finally, security teams should consider conducting regular penetration testing and red teaming exercises to identify and remediate potential vulnerabilities before they can be exploited by attackers. The goal is to ensure that the organization is prepared to respond to potential security incidents and to minimize the risk of exploitation. This may involve implementing additional security controls, conducting regular security audits and vulnerability assessments, and providing security awareness training to employees. By prioritizing verification and remediation efforts, organizations can minimize the risk of exploitation and protect their systems and data from potential attacks. The HIGH CVSS score of 8.3 indicates a high level of severity, and organizations should take immediate action to rem.

Technical summary

OMICRON StationScout before version 3.05 contains a cryptographic timing side-channel vulnerability in the backend authentication mechanism. This may allow an unauthenticated attacker to forge valid authentication credentials, bypass authentication and authorization, and impersonate legitimate clients. An attacker could gain full access to the system configuration, allowing modification, reset, or unauthorized alteration of system parameters or injecting network traffic into the connected network. The vulnerability has a HIGH CVSS score of 8.3, indicating a high level of severity.

Defensive priority

High-priority defensive actions are required due to the HIGH CVSS score of 8.3 and potential for authentication bypass.

Recommended defensive actions

• Verify system configurations and inventory for OMICRON StationScout versions prior to 3.05
• Implement compensating controls to monitor and restrict access to system parameters
• Monitor for unauthorized alterations of system parameters or network traffic injection
• Apply vendor remediation when available
• Conduct regular security audits and vulnerability assessments
• Review relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

Evidence is limited; primary official records indicate a cryptographic timing side-channel vulnerability in OMICRON StationScout before version 3.05. Verification of system configurations and inventory checks are recommended. Limited evidence suggests that affected deployments may exist; defenders should verify system configurations and inventory for OMICRON StationScout versions prior to 3.05.
