CVE-2025-2875
📋 TL;DR
This vulnerability allows unauthenticated attackers to manipulate a controller's webserver URL to access resources they shouldn't have access to, potentially exposing sensitive information. It affects Schneider Electric products with vulnerable web interfaces. Attackers can exploit this without credentials to breach confidentiality.
💻 Affected Systems
- Schneider Electric controllers with vulnerable web 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.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete loss of confidentiality with exposure of all web-accessible resources including configuration files, credentials, and sensitive operational data.
Likely Case
Unauthorized access to some web resources, potentially exposing configuration details or limited sensitive information.
If Mitigated
Minimal impact if proper network segmentation and access controls prevent external access to the vulnerable interface.
🎯 Exploit Status
Exploitation involves URL manipulation which is typically straightforward
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to vendor advisory for specific fixed versions

Restart Required: Yes
Instructions:
1. Review vendor advisory for affected products. 2. Download and apply the recommended firmware update. 3. Restart the controller to apply changes. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Network Segmentation
allIsolate vulnerable controllers from untrusted networks
Access Control Lists
allImplement firewall rules to restrict access to controller web interface
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable controllers
- Deploy web application firewall (WAF) rules to block URL manipulation attempts
🔍 How to Verify
Check if Vulnerable:
Check if Schneider Electric controller web interface is accessible and test for URL path traversal/manipulationCheck Version:
Check web interface status page or use vendor-specific CLI commandsVerify Fix Applied:
Verify firmware version matches vendor's fixed version and test that URL manipulation no longer works📡 Detection & Monitoring
Log Indicators:
- Unusual URL patterns in web server logs
- Access attempts to restricted paths
Network Indicators:
- HTTP requests with manipulated URLs to controller IPs
- Unusual traffic patterns to controller web ports
