🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: Yes
Instructions:
1. Check SRS project repository for security updates. 2. Upgrade to patched version when available. 3. Restart SRS service after upgrade.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict network access to SRS servers using firewall rules
iptables -A INPUT -p tcp --dport [SRS_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [SRS_PORT] -j DROP
Reverse Proxy with Request Filtering
allPlace SRS behind reverse proxy that filters malicious requests
# Configure nginx/apache to proxy requests to SRS with strict request validation
🧯 If You Can't Patch
- Isolate vulnerable servers in separate network segment with strict firewall rules
- Implement application-level firewall or WAF to filter malicious requests
🔍 How to Verify
Check if Vulnerable:
Check SRS version using: srs --version or check configuration files for version string
Check Version:
srs --version 2>/dev/null || grep -i version /usr/local/srs/conf/srs.conf
Verify Fix Applied:
Verify upgraded version is not in affected range: RS/4.0.268(Leo) or SRS/4.0.195(Leo)
