CVE-2026-76147 · Severity: info · Published 2026-10-01

Genian NAC and ZTNA are network access control and zero-trust network access products that manage device authentication and network policy. A vulnerability in the agent upgrade mechanism allows a privileged attacker to upload a malicious ZIP file that exploits path traversal to write files outside the intended directory, combined with Tomcat's auto-deployment feature, this can lead to remote code execution on the server.

## Technical details

The vulnerability is a ZIP Slip path traversal flaw in the agent upgrade feature caused by insufficient authorization and integrity verification of uploaded files. An attacker with high privileges can craft a ZIP archive containing relative paths (e.g., ../../../) to write files into arbitrary locations. When combined with Tomcat's automatic deployment functionality and external proxy path configuration, this allows execution of malicious code on the vulnerable system.

## Affected products
