CVE-2025-11565
📋 TL;DR
A path traversal vulnerability in Schneider Electric systems allows local network Web Admin users to manipulate file paths via POST /REST/UpdateJRE requests, potentially gaining elevated system access. This affects Schneider Electric products with vulnerable web interfaces accessible to authenticated local users.
💻 Affected Systems
- Schneider Electric products with vulnerable web admin interfaces
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative privileges, allowing installation of malicious software, data theft, or disruption of industrial control systems.
Likely Case
Unauthorized file access or modification, potentially leading to service disruption or credential harvesting from the affected system.
If Mitigated
Limited impact if proper network segmentation and access controls prevent local attackers from reaching the vulnerable endpoint.
🎯 Exploit Status
Exploitation requires authenticated Web Admin access and knowledge of vulnerable endpoint

🔧 Temporary Workarounds
Network Segmentation
allIsolate affected systems from general network access
Access Control Restriction
allLimit Web Admin access to trusted users only
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems
- Enforce least privilege access controls for Web Admin users
🔍 How to Verify
Check if Vulnerable:
Check if system responds to POST /REST/UpdateJRE requests and validate path traversal protectionsCheck Version:
Check system web interface or vendor-specific version commandVerify Fix Applied:
Verify patch version installed and test that path traversal attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /REST/UpdateJRE
- File access attempts outside expected directories
Network Indicators:
- POST requests to /REST/UpdateJRE with suspicious path parameters
SIEM Query:
web_access_logs WHERE uri_path CONTAINS '/REST/UpdateJRE' AND (request_body CONTAINS '../' OR request_body CONTAINS '..\\')
