🔍 How to Verify
Check if Vulnerable:
Test by accessing /index.php?mod=textviewer&src=../../../etc/passwd and checking for file content in responseCheck Version:
Check Pichome version in configuration files or admin interfaceVerify Fix Applied:
Attempt the same test after applying fixes - should return error or sanitized output📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /index.php?mod=textviewer with ../ sequences in parameters
- Unusual file access patterns from web server process
Network Indicators:
- HTTP requests containing path traversal sequences like ../ or ..\
- Responses containing unexpected file contents
SIEM Query:
