CVE-2025-5740
📋 TL;DR
This path traversal vulnerability allows authenticated users on a web server to write arbitrary files by manipulating file paths. It affects Schneider Electric products with web interfaces where authenticated users can access file upload or manipulation functionality. The vulnerability could lead to system compromise if exploited.
💻 Affected Systems
- Schneider Electric products with web interfaces (specific products not detailed in provided reference)
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary file writes leading to remote code execution, data theft, or complete system takeover.
Likely Case
Unauthorized file writes allowing privilege escalation, data manipulation, or service disruption.
If Mitigated
Limited impact with proper file system permissions and web server sandboxing, potentially only allowing writes to non-critical directories.
🎯 Exploit Status
Exploitation requires authenticated access but path traversal techniques are well-documented and relatively simple to implement.
🛠️ Fix & Mitigation
✅ Official Fix

Vendor Advisory: https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2025-161-03&p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2025-161-03.pdf
Restart Required: Yes
Instructions:
1. Review the Schneider Electric security advisory SEVD-2025-161-03. 2. Identify affected products and versions. 3. Apply the vendor-provided patches or firmware updates. 4. Restart affected systems as required.
🔧 Temporary Workarounds
Restrict web interface access
allLimit access to the web interface to only trusted networks and users
Implement input validation
allAdd server-side validation to reject path traversal sequences in file operations
🧯 If You Can't Patch
- Implement network segmentation to isolate affected systems from critical networks
- Enable detailed logging and monitoring for file write operations and path traversal attempts
🔍 How to Verify
Check if Vulnerable:
Check if your Schneider Electric product version matches affected versions listed in SEVD-2025-161-03 advisoryCheck Version:
Product-specific command; typically available through web interface or CLI depending on productVerify Fix Applied:
Verify patch installation by checking version numbers against patched versions in vendor advisory📡 Detection & Monitoring
Log Indicators:
- Unusual file write operations
- Path traversal patterns in web logs (../, ..\, %2e%2e%2f)
- Multiple failed authentication attempts followed by successful file operations
Network Indicators:
- HTTP requests containing path traversal sequences to file upload endpoints
- Unusual file transfer patterns from web server
SIEM Query:
