Quick assessment

Affected
Red Hat Red Hat Directory Server 11.7 E4S for RHEL 8
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 389 Directory Server 中发现了一个缺陷。SELFDN ACI 绑定规则评估器错误地将匿名 LDAP 客户端的空绑定 DN 与一个空的存储属性值进行匹配，使得未认证的客户端能够满足本应要求匹配已认证身份的访问控制检查。这使得匿名 LDAP 客户端可以执行本应由基于 SELFDN 的 ACI 限制为特定已认证用户才能执行的操作，例如添加或修改目录条目。

Vulnerability Title
389-ds-base: 389-ds: anonymous ldap client can defeat selfdn aci bind-rule checks via empty bind dn
Source: CVE Program / CVE List V5
Vulnerability 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.
