🔍 How to Verify
Check if Vulnerable:
Check if running jshERP version 3.6 or earlier. Review application logs for plugin installation attempts.Check Version:
Check application version in jshERP interface or configuration filesVerify Fix Applied:
Test if path traversal attempts are properly blocked. Verify no unauthorized file access occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual plugin installation attempts
- Path traversal patterns in URLs
- File access errors in unusual directories
Network Indicators:
- HTTP requests to /jshERP-boot/plugin/installByPath with suspicious path parameters
SIEM Query:
source="jshERP" AND (url="*installByPath*" AND (path="*../*" OR path="*..\\*"))
