AI Analysis

Impact

This vulnerability exists in the Oracle Unified Directory component of Oracle Fusion Middleware. A low‑privileged attacker with network access via LDAP can exploit a flaw in the LDAP service, leading to a full takeover of the directory service. The compromise results in loss of confidentiality, integrity, and availability of data stored within Oracle Unified Directory.

Affected Systems

The affected product is Oracle Unified Directory from Oracle Corporation. Versions 12.2.1.4.0 and 14.1.2.1.0 are vulnerable to this issue.

Risk and Exploitability

The CVSS v3.1 Base Score of 8.8 indicates high severity, while the EPSS score of less than 1% indicates a low current exploitation probability. The vulnerability is not listed in CISA’s KEV catalog. Attackers can exploit this weakness through the LDAP protocol using low privilege credentials or minimal access rights, as the description states that a low privileged attacker with network access via LDAP can compromise the directory service. This presents a significant risk to organizations that expose LDAP services without proper isolation or access controls.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Oracle’s official patch or upgrade to a non‑vulnerable version of Oracle Unified Directory.
  • Restrict LDAP network ports to trusted hosts or implement firewall rules to isolate the service from the public network.
  • Disable LDAP anonymous binding and enforce least‑privilege ACLs to limit the impact of compromised credentials.
  • Monitor LDAP access logs for unusual activity to detect potential exploitation attempts.
