Technical details

A vulnerability exists in the OUD Core component of Oracle Unified Directory (versions 12.2.1.4.0 and 14.1.2.1.0). The flaw is exploitable by a low-privileged attacker with network access via the LDAP protocol. While the attack complexity is high, a successful exploit results in a scope change (S:C), potentially impacting integrated products that rely on the directory service. Attackers can achieve full confidentiality and integrity compromise, allowing for the unauthorized creation, deletion, or modification of all accessible directory data. Users are advised to refer to the Oracle Critical Patch Update for July 2026 for remediation.
