CVE-2025-67013
📋 TL;DR
This CVE describes a Cross-Site Request Forgery (CSRF) vulnerability in ETL Systems Ltd DEXTRA Series Digital L-Band Distribution System web management interface. Attackers can trick authenticated administrators into performing unauthorized configuration changes without their knowledge. This affects organizations using the vulnerable version of this satellite communication equipment management system.
💻 Affected Systems
- ETL Systems Ltd DEXTRA Series Digital L-Band Distribution System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers reconfigure the distribution system to disrupt satellite communications, reroute signals, or disable critical functionality.
Likely Case
Unauthorized configuration changes leading to service disruption, signal manipulation, or system instability requiring manual intervention to restore proper operation.
If Mitigated
Limited impact with proper network segmentation and access controls, though configuration changes could still occur if administrators are tricked.
🎯 Exploit Status
CSRF attacks require the victim to be authenticated to the management interface. The GitHub reference contains research demonstrating the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.etlsystems.com/
Restart Required: No
Instructions:
Check vendor website for security updates. If available, download and apply the patch following vendor instructions.
🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd CSRF protection tokens to all configuration endpoints in the web interface
Requires code modification - consult vendor or developer
Origin/Referer Validation
allImplement server-side validation of Origin and Referer headers for all POST requests
Requires code modification - consult vendor or developer
🧯 If You Can't Patch
- Segment the management interface to internal network only and restrict access to authorized administrators
- Implement web application firewall (WAF) rules to detect and block CSRF attempts
🔍 How to Verify
Check if Vulnerable:
Test configuration endpoints for CSRF tokens and Origin/Referer validation using tools like Burp Suite or OWASP ZAP
Check Version:
Check system version through web interface or consult vendor documentation
Verify Fix Applied:
Verify that all configuration endpoints now require CSRF tokens and validate Origin/Referer headers
📡 Detection & Monitoring
Log Indicators:
- Unexpected configuration changes
- Multiple failed authentication attempts followed by configuration requests
- Requests from unusual IP addresses to configuration endpoints
Network Indicators:
- HTTP POST requests to configuration endpoints without CSRF tokens
- Requests with mismatched Origin/Referer headers
SIEM Query:
source="web_logs" AND (uri="/config/*" OR uri="/admin/*") AND method="POST" AND (NOT csrf_token=*)
