Description
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, ommit d4d10006 ("Expand validation to block .. in config_file_name and configver for improved security") added a line in app/modules/config/config.py:462. This is tuple-membership, not substring containment — '..' in (a, b, c) evaluates to True only if any of a, b, c is equal to the literal string '..'. For any realistic path-traversal payload (../../etc/passwd, ..\\..\\etc\\passwd, etc.) the check returns False and the patch silently lets the payload through. At time of publication, there are no publicly available patches.
Problem types
