🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Disable XXE Processing
windowsConfigure XML parser to disable external entity resolution
Modify web.config or application settings to set XmlResolver to null
Set DTD processing to Prohibit or Ignore
Input Validation
allImplement strict input validation to reject XML with external entities
Add input validation filters for XML content
Use allowlists for acceptable XML structures
🧯 If You Can't Patch
- Implement WAF rules to block XXE payloads at the network perimeter
- Restrict network access to the vulnerable endpoint using firewall rules
🔍 How to Verify
Check if Vulnerable:
Test by sending XML with external entity references to ProjectScheduleDelete.aspx endpointCheck Version:
Check application version in web interface or configuration filesVerify Fix Applied:
Verify XML parser configuration disables external entity resolution📡 Detection & Monitoring
