CVE-2026-45564 roxy-wi CVE debrief

CVE-2026-45564 is a high-severity vulnerability in Roxy-WI, a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. The vulnerability affects versions 8.2.6.4 and prior. An authenticated user with a role less than or equal to 3 (i.e., a 'user' role) can exploit this vulnerability to inject commands. The vulnerability arises from the interpolation of the URL-path `configver` parameter directly into a config-version path, which is then passed to `os.system`. Specifically, the `configver` parameter is not properly sanitized or validated, allowing an attacker to inject arbitrary commands. At the time of publication, there are no publicly available patches for this vulnerability.

Who should care

Administrators and users of Roxy-WI, especially those with user-level access, should be aware of this vulnerability and take necessary precautions to mitigate the risk.

Technical summary

The vulnerability is caused by the lack of proper sanitization and validation of the `configver` parameter in the `POST /config/versions/<service>/<server_ip>/<configver>/save` endpoint. This allows an authenticated user with role <= 3 to inject arbitrary commands, which are then executed by `os.system`.

Defensive priority

High

Recommended defensive actions

  • Apply patches or updates as soon as they become available.
  • Restrict access to the affected endpoint to only trusted users and roles.
  • Implement additional security measures, such as input validation and sanitization, to prevent similar vulnerabilities.
