CVE-2025-48017
📋 TL;DR
This vulnerability allows attackers to modify and upload arbitrary files by exploiting improper pathname limitations in Circuit Provisioning and File Import applications. It affects SEL (Schweitzer Engineering Laboratories) software products that include these applications. Attackers could potentially gain unauthorized access or disrupt operations.
💻 Affected Systems
- SEL Circuit Provisioning and File Import applications
⚠️ 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
Complete system compromise allowing remote code execution, data theft, or service disruption through arbitrary file uploads.
Likely Case
Unauthorized file modification leading to configuration changes, data corruption, or privilege escalation.
If Mitigated
Limited impact with proper file permission controls and network segmentation in place.
🎯 Exploit Status
Path traversal vulnerabilities typically have low complexity but may require authentication; check SEL advisory for specifics
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SEL's latest software versions at provided URL
Vendor Advisory: https://selinc.com/products/software/latest-software-versions/
Restart Required: Yes
Instructions:
1. Visit SEL's software versions page. 2. Identify affected products. 3. Download and install latest patched versions. 4. Restart affected services/systems.
🔧 Temporary Workarounds
Restrict File Upload Permissions
linuxLimit file upload capabilities to trusted directories with strict permissions
chmod 750 /path/to/upload/directory
chown root:root /path/to/upload/directory
Implement Input Validation
allAdd path traversal validation to file upload functions
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems
- Deploy web application firewall with path traversal protection rules
🔍 How to Verify
Check if Vulnerable:
Check application version against SEL's advisory; test file upload with path traversal payloads (e.g., ../../../etc/passwd)Check Version:
Check application interface or configuration files for version informationVerify Fix Applied:
Verify installed version matches patched version; retest with path traversal attempts📡 Detection & Monitoring
Log Indicators:
- Unusual file upload patterns
- Path traversal strings in file operations
- Failed authentication attempts followed by file uploads
Network Indicators:
- HTTP requests containing ../ sequences in file upload parameters
- Unusual file transfer patterns to/from affected systems
