CVE-2025-43928
📋 TL;DR
Infodraw Media Relay Service 7.1.0.0 contains a path traversal vulnerability in its web server on port 12654. Attackers can read arbitrary files, including ServerParameters.xml which may contain administrator credentials in cleartext or MD5 hashes. Organizations using Infodraw MRS 7.1.0.0 are affected.
💻 Affected Systems
- Infodraw Media Relay Service (MRS)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via credential theft leading to unauthorized access, data exfiltration, or lateral movement within the network.
Likely Case
Administrative credential disclosure allowing unauthorized access to the MRS system and potentially connected surveillance infrastructure.
If Mitigated
Limited information disclosure if credentials are properly secured with strong hashing and file permissions restrict sensitive data access.
🎯 Exploit Status
Exploitation involves simple HTTP requests with directory traversal sequences in the username parameter. Public research presentations demonstrate the technique.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Contact Infodraw for updated version information and security patches.
🔧 Temporary Workarounds
Network Access Control
allRestrict access to port 12654/TCP using firewall rules to only trusted IP addresses.
# Windows Firewall: New-NetFirewallRule -DisplayName "Block MRS Port" -Direction Inbound -LocalPort 12654 -Protocol TCP -Action Block
# Linux iptables: iptables -A INPUT -p tcp --dport 12654 -j DROP
File Permission Hardening
allSet restrictive permissions on ServerParameters.xml and other sensitive files to prevent unauthorized reading.
# Windows: icacls "C:\Path\To\ServerParameters.xml" /deny Everyone:(R)
# Linux: chmod 600 /path/to/ServerParameters.xml
🧯 If You Can't Patch
- Isolate the MRS server in a dedicated network segment with strict firewall rules limiting inbound/outbound connections.
- Implement application-level monitoring for suspicious file access patterns on port 12654 and alert on directory traversal attempts.
🔍 How to Verify
Check if Vulnerable:
Send an HTTP request to http://[target]:12654 with a username parameter containing directory traversal sequences (e.g., ../ServerParameters.xml) and check if sensitive files are returned.Check Version:
Check the MRS application interface or installation directory for version information (typically 7.1.0.0).Verify Fix Applied:
Attempt the same exploitation after applying workarounds; successful requests should be blocked or return error responses.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to port 12654 containing ../ sequences in parameters
- Access to ServerParameters.xml file from unexpected sources
Network Indicators:
- Unusual outbound connections from the MRS server following credential theft
- Traffic patterns indicating file enumeration attempts
