Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions up to and including 8.2.8.2, when LDAP authentication is enabled, Roxy-WI constructs an LDAP search filter by directly concatenating the user-supplied login username into the filter string without escaping LDAP special characters. An unauthenticated attacker can inject LDAP filter metacharacters into the username field to manipulate the search query, cause the directory to return an unintended user entry, and bypass authentication entirely — gaining access to the application without knowing any valid password. As of time of publication, no known patches are available.
This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability none.
The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
