• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-862

Description

A flaw was found in 389 Directory Server. The CleanAllRUV and Abort CleanAllRUV replication-maintenance extended operations perform no authorization check, allowing an unauthenticated remote attacker to invoke them when nsslapd-allow-anonymous-access is enabled (the default), or any authenticated low-privilege user to invoke them otherwise. This allows removal of a replica ID from replication metadata, purging of changelog records, and interruption of administrator-initiated cleanup, which can leave replication inconsistent or unavailable.
