FKIE_CVE-2026-45566

Vulnerability from fkie_nvd - Published: 2026-06-10 16:17 - Updated: 2026-06-17 10:52
Severity
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the login flow allow-lists next URLs by rejecting strings containing https:// or http:// substrings, then constructs https://{request.host}{next_url} and the JS client redirects via window.location.replace(). The block does not consider the userinfo@host syntax. next=@evil.example/path produces https://victim.example@evil.example/path, which all modern browsers route to evil.example. At time of publication, there are no publicly available patches.
