Description
MRBS before 1.13.0 contains an LDAP injection vulnerability in web/lib/MRBS/Auth/AuthLdap.php that interpolates unescaped login usernames into DN search and group-membership filters. Attackers with valid directory credentials outside the required group can submit crafted usernames that make the group filter always true, bypassing access restrictions.
