Technical details
An LDAP injection vulnerability exists in Roxy-WI versions 8.2.6.4 and prior within the `get_ldap_email` function located in `app/modules/roxywi/user.py`. The application constructs LDAP search filters using f-string concatenation with the `username` URL path parameter without performing input validation or LDAP escaping. An attacker with high privileges (Level 2 Admin/Group Admin) can inject LDAP metacharacters (e.g., `*)(mail=*)(cn=*`) to manipulate the query logic. This allows for the enumeration and harvesting of LDAP attributes outside the intended scope of the single user record. As of the advisory date, no official patches are available, though manual remediation involves using `ldap.filter.escape_filter_chars`.
