🔍 How to Verify
Check if Vulnerable:
Check if system runs Zucchetti Ad Hoc Infinity version 2.4 and has /servlet/Report and /jsp/zimg_upload.jsp endpoints accessible.Check Version:
Check application interface or configuration files for version information.Verify Fix Applied:
Verify version is updated beyond 2.4 and test that file upload to /jsp/zimg_upload.jsp is properly validated/rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /jsp/zimg_upload.jsp
- Access to /servlet/Report with file inclusion parameters
- JSP file execution from unusual locations
Network Indicators:
- HTTP POST requests to /jsp/zimg_upload.jsp with JSP content
- HTTP requests to /servlet/Report with file path parameters
SIEM Query:
source="web_logs" AND (uri_path="/jsp/zimg_upload.jsp" OR uri_path="/servlet/Report") AND (file_extension="jsp" OR param_contains="file=")
