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 an unauthenticated attacker via the LDAP protocol over a network. Although the attack complexity is rated as high, a successful exploit results in a scope change (S:C), meaning the impact can extend beyond the directory service itself to other integrated systems. Attackers can achieve unauthorized creation, deletion, or modification of all data within the directory, as well as complete read access to sensitive information. The vulnerability primarily impacts confidentiality and integrity, with no reported impact on availability.
