Vulnerability from cvelistv5 – Published: 2026-07-31 09:18 – Updated: 2026-07-31 23:24

Title

389-ds-base: 389-ds-base: pre-auth ldap filter injection in cleanallruv status check

Summary

A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.

Severity

7.5 (High)
