MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Network access via TLS to the Oracle Identity Manager Connector Core component is required - the attack is delivered over the connector's TLS-exposed service port. High attack complexity (AC:H) means exploitation is not straightforward: Oracle's CPU language ('difficult to exploit') indicates that specific conditions must align, potentially including a precise protocol state, a race condition, or a man-in-the-middle position on the TLS channel. No authentication is required (PR:N) and no user interaction is needed (UI:N). Exploitation is limited by the AC:H requirement - automated, opportunistic exploitation at scale is unlikely. Defenders should note that the actual technical precondition driving AC:H is not disclosed in available data; the CWE is unspecified, and Oracle CPU advisories rarely elaborate on the complexity trigger. Verify with Oracle support whether the complexity condition relates to network positioning, protocol sequencing, or a configuration-dependent code path. |
| Impact | The CVSS 3.1 score of 8.1 reflects genuine severity: network-accessible, no authentication, no user interaction, and complete C/H/I/A impact. The sole moderating factor is AC:H - Oracle's own description characterizes this as 'difficult to exploit,' which historically in Oracle CPU advisories correlates with requirements such as race conditions, specific protocol state, man-in-the-middle positioning, or precise timing. No EPSS score was provided in the input data, preventing probabilistic exploitation likelihood assessment; this gap should be resolved by checking NVD or FIRST directly. There is no CISA KEV listing and no reported POC, so exploitation appears theoretical at time of analysis. The AC:H designation meaningfully lowers the population of actors capable of weaponizing this - opportunistic mass scanning is unlikely to succeed, but sophisticated nation-state or well-resourced criminal actors targeting identity infrastructure could invest the effort. Identity management connectors are high-value targets because compromising them enables downstream provisioning manipulation across all connected systems. Organizations running OIM in internet-exposed or DMZ configurations face higher realistic risk than those with strict network segmentation. |
| Exploit ScenarioDerived | A remote unauthenticated attacker with network-level access to the OIM Connector TLS port crafts a malicious TLS payload or protocol interaction targeting a flaw in the Core component - likely requiring specific protocol state, timing, or a particular message sequence given the AC:H rating. If the attack succeeds, the attacker achieves full control of the Identity Manager Connector process, enabling manipulation of identity provisioning flows to all connected target systems. No public POC has been identified, but the TLS exposure means any attacker who can route packets to the service port is within attack range. |

Alert meAnalysisAIv1 – Aug 19, 2026
Full takeover of Oracle Identity Manager Connector is achievable by an unauthenticated remote attacker communicating over TLS, affecting the Core component of versions 12.2.1.4.0 and 14.1.2.1.0 under Oracle Fusion Middleware. The CVSS vector confirms network reachability with no privileges or user interaction required, though high attack complexity (AC:H) indicates that exploitation demands specific conditions beyond a simple point-and-shoot approach. No public exploit code or CISA KEV listing has been identified at time of analysis, but the complete confidentiality, integrity, and availability impact makes successful exploitation a full system compromise.
RemediationAI
Apply Oracle's Critical Security Patch Update (CPU) for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability for both affected versions (12.2.1.4.0 and 14.1.2.1.0). The advisory does not specify an exact patched release version in the available data, so administrators should consult the Oracle CPU directly to confirm the minimum patched build. As a compensating control prior to patching, restrict network access to the OIM Connector TLS endpoint using firewall rules or network ACLs so that only authorized provisioning hosts can reach the service - this directly mitigates the AV:N attack vector without disabling connector functionality. Additionally, audit TLS listener exposure: if the connector endpoint is reachable from internet-facing segments, move it behind a network perimeter control immediately. These controls reduce exposure but do not eliminate the vulnerability; patching remains the definitive remediation.

Technical ContextAI · show details
Oracle Identity Manager (OIM) Connector is a Fusion Middleware component responsible for provisioning and reconciling identities between OIM and connected target systems (directories, HR systems, applications). The Core component handles the fundamental connector lifecycle, communication, and data exchange layer. Attacks are conducted via TLS, meaning the vulnerability resides in the TLS-exposed service interface of the connector framework rather than in web UI or database tiers. The CWE classification is not specified in available data, preventing precise root-cause categorization; however, the combination of network vector, no authentication requirement, and full-takeover impact is consistent with classes such as deserialization flaws, protocol-level authentication bypass, or critical logic errors in the TLS handler. Affected CPE-identifiable versions are Oracle Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0.

DescriptionCVE.org
Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle Identity Manager Connector. Successful attacks of this vulnerability can result in takeover of Oracle Identity Manager Connector. CVSS 3.1 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
Executive ViewAI
Oracle Identity Manager Connector (versions 12.2.1.4.0 and 14.1.2.1.0) contains a critical vulnerability enabling unauthenticated remote attackers to achieve complete system compromise of the identity management infrastructure. Organizations running affected Fusion Middleware deployments face direct compromise of identity and access controls, creating cascading risk across all dependent applications and data access policies.
No vendor-released patch identified at time of analysis. Interim mitigations include network segmentation to restrict inbound TLS connections to trusted sources only, disable unnecessary remote access protocols, implement connection rate-limiting and authentication strengthening on upstream systems, enable comprehensive audit logging for all Connector access, and deploy additional access controls on downstream applications dependent on this Connector to minimize blast radius if compromise occurs.
