Executive Summary

This vulnerability is an unrestricted file upload flaw in Genian SSL PNS caused by insufficient file extension and integrity verification. Attackers can bypass checks by manipulating file extensions to .svi or .jar, uploading dangerous files that are not official patches. The issue is classified under CWE-434 and affects versions before 5.0.0, including the watchcat-ui component.

Detection Guidance

Check for unauthorized file uploads in Genian SSL PNS directories, particularly files with .svi or .jar extensions outside official patch locations. Inspect logs for upload attempts with manipulated extensions.

Impact Analysis

Mitigation Strategies

Upgrade Genian SSL PNS to version 5.0.0 or later. Implement strict file extension validation and integrity checks for uploaded files. Restrict upload permissions to authorized users only.
