3DescriptionGitHub Advisory
Moonraker is a Python web server providing API access to Klipper 3D printing firmware. In versions 0.9.3 and below, instances configured with the "ldap" component enabled are vulnerable to LDAP search filter injection techniques via the login endpoint. The 401 error response message can be used to determine whether or not a search was successful, allowing for brute force methods to discover LDAP entries on the server such as user IDs and user attributes. This issue has been fixed in version 0.10.0.
AnalysisAI
Moonraker versions 0.9.3 and below with LDAP authentication enabled are susceptible to LDAP injection attacks through the login endpoint, enabling attackers to enumerate valid user IDs and attributes via response analysis. An unauthenticated remote attacker can exploit this vulnerability to discover LDAP directory information without requiring valid credentials. A patch is available in version 0.10.0 and later.
Technical ContextAI
Classified as CWE-90 (LDAP Injection). Affects the login component of Moonraker. Moonraker is a Python web server providing API access to Klipper 3D printing firmware.
