CVE-2022-1949Network attack vector

Unauthenticated directory data disclosure via optimized filters

Published Jun 1, 2022 · Updated Aug 3, 2024

Access control bypass in 389 Directory Server 2.0 allows remote attackers to read restricted directory data through crafted LDAP filters. The LDAP filter optimizer accepts a shortcut condition without preserving the ACI check, so a crafted query returns entries or attributes that its anonymous requester cannot search. No credentials or user interaction are required; exposed data can include userPassword hashes and other sensitive directory values.
