CyberRota Analysis
AI-GeneratedOpenDJ versions prior to 5.1.2 are vulnerable due to improper handling of the SASL PLAIN authorization identity, allowing authenticated users with the PROXIED_AUTH privilege to impersonate other users outside their permitted scope. This critical vulnerability can lead to unauthorized access and identity escalation, posing significant risks to directory services. Organizations using affected versions should prioritize upgrading to 5.1.2 or later to mitigate potential exploitation.

Original NVD Description
OpenDJ is an LDAPv3 compliant directory service. Prior to 5.1.2, the SASL PLAIN authorization identity path in opendj-server-legacy/src/main/java/org/opends/server/extensions/PlainSASLMechanismHandler.java checked the PROXIED_AUTH privilege but did not evaluate the mayProxy proxy ACI scope when an authzid resolved to a different user. Both dn: and u: or bare authzid forms could therefore let an authenticated account holding PROXIED_AUTH assume any resolvable non-root identity outside the identities permitted by its proxy ACI. The fix returns INVALID_CREDENTIALS (49) before password verification when the target authorization identity is not permitted. This issue is fixed in version 5.1.2.
