🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider workarounds or alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for user_id parameter to prevent deserialization attacks
Modify classes/class.database.php to validate/sanitize user_id input before processing
WAF Rule Implementation
allDeploy web application firewall rules to block deserialization attempts
Add WAF rule to detect and block serialized object patterns in requests
🧯 If You Can't Patch
- Isolate pmTicket instance behind strict network segmentation with no internet access
- Implement application-level input validation and disable vulnerable functionality if possible
🔍 How to Verify
Check if Vulnerable:
Check if your pmTicket installation includes commit hash 2ef379da2075f4761a2c9029cf91d073474e7486 or earlier in git historyCheck Version:
git log --oneline -1Verify Fix Applied:
Test with known exploit payloads to ensure deserialization is no longer possible📡 Detection & Monitoring
Log Indicators:
- Unusual deserialization errors in application logs
- Suspicious user_id parameter values in access logs
Network Indicators:
- HTTP requests with serialized objects in parameters
- Unusual outbound connections from pmTicket server
SIEM Query:
source="pmTicket" AND ("deserialization" OR "user_id" contains "O:" OR "C:")
