Deeper analysis
Roxy-wi is an open source web interface for managing HAProxy, Nginx, Apache, and Keepalived servers. CVE-2022-31126 is a remote code execution vulnerability that stems from improper input handling (CWE-74) in the /app/options.py endpoint. It affects all versions prior to 6.1.1.0 and carries a CVSS 3.1 score of 10.0, reflecting network-accessible, unauthenticated, and high-impact exploitation.
An unauthenticated attacker can send a specially crafted HTTP request to the affected endpoint and obtain arbitrary code execution on the server. Because the attack requires no credentials or user interaction and can cross trust boundaries, it enables complete compromise of the Roxy-wi instance and any managed load-balancer or web-server configurations.
The project’s GitHub Security Advisory (GHSA-mh86-878h-43c9) states there are no known workarounds and explicitly advises users to upgrade immediately to version 6.1.1.0 or later. The EPSS score remains elevated, with a current value of 0.8914 and a recorded peak of 0.9156.
