Executive Summary

This is a path traversal (ZIP Slip) vulnerability in Genian NAC/ZTNA caused by weak authorization and integrity checks during agent upgrades. Attackers exploit this by manipulating file paths in ZIP archives to execute arbitrary code on the system.

Detection Guidance

Check for unauthorized agent upgrades or unexpected file modifications in Genian NAC/ZTNA directories. Monitor network traffic for suspicious ZIP file downloads or Tomcat deployment activities. Review system logs for unusual code execution patterns.

Impact Analysis

An attacker could gain control of the affected system, modify data, or install malware. The vulnerability requires high privileges but allows unauthorized system changes, potentially leading to full compromise of Genian NAC/ZTNA deployments.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating integrity and confidentiality requirements in GDPR and HIPAA. Organizations using vulnerable versions may face compliance violations and potential fines.

Mitigation Strategies

Upgrade Genian NAC to version 4.0.175 (Revision 148817) or higher, Genian ZTNA to 6.0.46 or higher, and Genian NAC 5.0.x to 5.0.86 or higher. Disable automatic Tomcat deployment and external proxy paths until patched.
