CVE-2025-41771 Phoenix Contact CVE debrief

Who should care

Organizations using the affected controller's web interface, security teams responsible for monitoring and patching vulnerabilities, and operators of the affected system should be aware of this vulnerability and take necessary actions to mitigate it. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Technical summary

The vulnerability allows an authenticated attacker with low privileges to access an endpoint in the controller's web interface that is vulnerable to SQL injection. The impact is limited to the system's notification functionality, which uses a SQLite database for storing notification messages. This functionality is crucial for system administrators to communicate important information. The vulnerability has a CVSS score of 5.3 and a severity of MEDIUM. To mitigate this vulnerability, organizations should verify and limit access to the vulnerable endpoint, implement input validation and sanitization for user input, and monitor notification functionality for potential anomalies.

Defensive priority

Medium priority due to limited impact on notification functionality

Recommended defensive actions

• Verify and limit access to the vulnerable endpoint
• Implement input validation and sanitization for user input
• Monitor notification functionality for potential anomalies
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check 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
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

Evidence from official CVE Program record and NIST NVD detail page. Limited information available on affected products and versions. The vulnerability affects a SQLite database used only for storing notification messages, which limits the impact to the system's notification functionality. Organizations should verify their exposure and review notification functionality for potential anomalies.
