CVSS v3

NVD

Description

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, get_ldap_email (app/modules/roxywi/user.py:120-157) builds the LDAP search filter via f-string concatenation. The username URL path parameter is taken verbatim — no checkAjaxInput, no LDAP escape — and inserted, a username like *)(mail=*)(cn=* injects additional clauses, allowing the admin to enumerate or harvest attributes outside the intended record. At time of publication, there are no publicly available patches.
