CyberRota Analysis
AI-GeneratedA vulnerability exists in 389 Directory Server, where the SELFDN ACI bind-rule evaluator improperly allows anonymous LDAP clients to bypass access control checks by matching an empty bind DN with an empty stored attribute value. This flaw enables unauthorized operations, such as adding or modifying directory entries, which should be restricted to authenticated users. Organizations using 389 Directory Server should prioritize addressing this issue to prevent potential unauthorized access and data manipulation.
Original NVD Description
A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user.
