Which versions of Nginx are affected by CVE-2026-45564?

Roxy-WI versions 8.2.6.4 and earlier contain an authenticated command injection vulnerability (CVSS 8.8) allowing low-privileged management interface users to execute arbitrary system commands on the…

How to fix or mitigate CVE-2026-45564?

Within 24 hours: Inventory all Roxy-WI deployments, confirm installed versions, and audit access logs for POST requests to /config/versions endpoints. Within 7 days: Implement network segmentation restricting Roxy-WI interface access to known administrative networks, disable or restrict user accounts with roles ≤ 3 to essential personnel only, and enable detailed logging of all POST requests. Within 30 days: Monitor vendor security advisories for patch availability; if no patch timeline is published, develop remediation plan including service decommissioning or air-gapped deployment.

DescriptionNVD

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, POST /config/versions/<service>/<server_ip>/<configver>/save interpolates the URL-path configver parameter directly into a config-version path that ends up at os.system(f"dos2unix -q {cfg}"). configver is not run through EscapedString (Pydantic doesn't validate path segments declared as str) and the surrounding .. block is the broken tuple-membership patch from GHSA-vapt-004. An authenticated user with role <= 3 ("user") therefore reaches a bin/sh -c command-injection sink. At time of publication, there are no publicly available patches.

AnalysisAI

Authenticated command injection in Roxy-WI versions 8.2.6.4 and prior allows low-privileged users (role <= 3, 'user') to execute arbitrary OS commands by abusing the configver URL-path parameter on POST /config/versions/<service>/<server_ip>/<configver>/save, which flows unsanitized into an os.system() call wrapping dos2unix. No public exploit identified at time of analysis, but the GHSA advisory is published and no vendor patch exists, leaving exposed instances at immediate risk of full compromise of the management interface host.
