2DescriptionCVE.org
Vulnerability in the Oracle Unified Directory product of Oracle Fusion Middleware (component: OUD Core). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Difficult to exploit vulnerability allows low privileged attacker with network access via LDAP to compromise Oracle Unified Directory. While the vulnerability is in Oracle Unified Directory, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Unified Directory. CVSS 3.1 Base Score 8.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).
AnalysisAI
Full takeover of Oracle Unified Directory (OUD) 12.2.1.4.0 and 14.1.2.1.0 is achievable by a low-privileged attacker with LDAP network access exploiting a flaw in the OUD Core component. The CVSS scope-change indicator (S:C) confirms that successful exploitation extends beyond the directory service itself, potentially compromising dependent Oracle Fusion Middleware applications that rely on OUD for identity and authentication services. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) network-level access to the Oracle Unified Directory LDAP service on port 389 or 636; (2) a valid low-privileged LDAP account - unauthenticated attackers cannot exploit this vulnerability, as the CVSS vector explicitly requires PR:L; and (3) high attack complexity (AC:H), meaning the attacker must satisfy undisclosed specific preconditions prior to or during the attack, which Oracle has not detailed publicly but may involve particular LDAP operation sequences, timing conditions, or configuration states. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.5 (High) reflects genuine severity: network delivery, no user interaction, full C/I/A impact, and scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply Oracle's August 2026 Critical Security Update addressing CVE-2026-60849, available at https://www.oracle.com/security-alerts/cspuaug2026.html; consult the advisory directly for the specific patch identifier and apply via Oracle's standard patching mechanism, as exact post-patch version numbers are not independently confirmed from the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all systems running OUD versions 12.2.1.4.0 or 14.1.2.1.0 and document business criticality; implement LDAP network access controls to restrict OUD connectivity to essential systems only and enable enhanced logging of authentication events. …
