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 | Exploitation requires the attacker to have access to the physical communication segment (adjacent network) attached to the hardware where the Oracle Identity Manager Connector executes - remote internet-only attackers cannot reach it (AV:A). No authentication is required (PR:N) and no user interaction is needed (UI:N), but the attack is rated high complexity (AC:H), meaning success depends on specific, hard-to-control conditions such as timing or connector state rather than a straightforward request. Only OIM Connector versions 12.2.1.4.0 and 14.1.2.1.0 running the Generic Unix Connector component are in scope; the adjacency requirement and high complexity are the primary factors limiting real-world exploitation. |
| Impact | The signals are mixed and should be weighed together rather than by score alone. CVSS 3.1 is 8.0 (High), but the vector reveals meaningful constraints: AV:A limits the attacker to the adjacent physical communication segment (not remote internet exploitation), and AC:H means Oracle itself rates the attack as difficult, likely requiring specific timing, state or environmental conditions. Offsetting factors that inflate the score are PR:N (no authentication), UI:N (no user interaction), and S:C (scope change into additional products) with High Integrity and High Availability impact; confidentiality impact is None. No EPSS score was provided, the CVE is not in CISA KEV, and no public proof-of-concept was identified, so there is no evidence of active or imminent exploitation. Net assessment: this is a genuine High-severity issue for organizations where the OIM Connector host shares a LAN segment with untrusted or lightly controlled devices, but the adjacent-only vector plus high complexity make it a lower practical priority than a network-reachable, low-complexity flaw. The 'Denial Of Service' tag aligns with the A:H impact. |
| Exploit ScenarioDerived | An attacker who has gained a foothold on a device sharing the local/adjacent network segment with the OIM Generic Unix Connector host sends specially crafted traffic to the connector's communication interface. Despite the high complexity, a successful attempt lets them tamper with provisioned account data or trigger a repeatable crash of the connector, and via the scope change disrupt or corrupt additional integrated identity systems. No public exploit code has been identified, so this would require original development against the adjacent interface. |

Alert meAnalysisAIv1 – Jul 22, 2026
Integrity and availability compromise in the Oracle Identity Manager Connector (Generic Unix Connector component) of Oracle Fusion Middleware allows an unauthenticated attacker positioned on the adjacent physical communication segment to modify, create or delete connector-accessible data and to cause a complete, repeatable denial of service. Versions 12.2.1.4.0 and 14.1.2.1.0 are affected, and because of a scope change the attack may significantly impact additional integrated products beyond the connector itself. There is no public exploit identified at time of analysis; the flaw is rated CVSS 3.1 8.0 despite high attack complexity.
RemediationAI
Apply the fixes delivered in the Oracle July 2026 Critical Patch Update; patch is available per vendor advisory (https://www.oracle.com/security-alerts/cpujul2026.html), though the intelligence provided does not contain an exact post-patch build number, so obtain the precise patched version from that advisory for your specific release train (12.2.1.4.0 or 14.1.2.1.0). Because exploitation requires access to the adjacent physical communication segment, the most effective compensating control until patching is network segmentation: isolate the host running the OIM Generic Unix Connector onto a dedicated, tightly controlled VLAN and restrict layer-2/adjacent access to only trusted management systems, accepting the operational overhead of managing an additional segment. Additionally restrict and monitor traffic to the connector's communication ports and keep the connector host off shared or user-accessible LAN segments; the trade-off is added routing/firewall complexity but a substantially reduced attack surface given the AV:A constraint.

Technical ContextAI · show details
The Oracle Identity Manager (OIM) Connector is an identity-provisioning bridge within Oracle Fusion Middleware that synchronizes accounts and entitlements between OIM and target systems; the affected component is the Generic Unix Connector, which manages user and account lifecycle operations against Unix-style target hosts. The CVSS vector (AV:A, S:C) indicates the weakness is reachable only from the adjacent network/physical segment attached to the hardware running the connector, and that successful exploitation crosses a trust boundary to affect other components. No CWE was assigned by NVD, but the described effects - unauthorized data creation/deletion/modification plus a complete hang or crash - are consistent with an unauthenticated protocol- or input-handling defect in the connector's communication layer that permits both data tampering and resource exhaustion. Oracle disclosed the issue through its July 2026 Critical Patch Update.

DescriptionCVE.org
Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: Generic Unix Connector). 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 access to the physical communication segment attached to the hardware where the Oracle Identity Manager Connector executes to compromise Oracle Identity Manager Connector. While the vulnerability is in Oracle Identity Manager Connector, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Identity Manager Connector accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Identity Manager Connector. CVSS 3.1 Base Score 8.0 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H).
Executive ViewAI
Oracle Identity Manager Connector (Generic Unix Connector) in Fusion Middleware versions 12.2.1.4.0 and 14.1.2.1.0 is vulnerable to network-adjacent attackers who can corrupt identity data, disrupt services, and compromise dependent systems-posing significant risk to identity governance and access control integrity across enterprise infrastructure. With no vendor patch available, organizations must immediately implement network controls to prevent exploitation. The vulnerability's expanding scope threatens not only the connector itself but potentially multiple integrated applications relying on it.
Network segmentation isolating Generic Unix Connector from untrusted adjacent networks; strict role-based access controls limiting administrative access to connector; comprehensive monitoring and alerting on connector data operations; disabling unnecessary connector features and integrations; isolation or air-gapping of critical identity infrastructure pending patch availability.
