Detailed vulnerability description
The vulnerability allows a remote attacker to bypass authentication.
The vulnerability exists due to LDAP injection in app/modules/roxywi/auth.py when processing login requests with a user-supplied username in an LDAP search filter. A remote attacker can send a specially crafted login request to bypass authentication.
Only instances with LDAP authentication enabled are vulnerable. If the LDAP server allows anonymous binds or unauthenticated simple binds, exploitation may succeed without a password.
