The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires network reachability to the HTTP interface of an Oracle Identity Manager Connector deployment running version 12.2.1.4.0 or 14.1.2.1.0 with the Generic Unix Connector component configured and active, plus a valid low-privileged authenticated session on the platform (CVSS PR:L). No user interaction is needed (UI:N) and attack complexity is low (AC:L), but exploitation is limited to environments that have actually deployed and configured the Generic Unix Connector - installations using only other connector types are not in scope - and the account must be able to invoke connector operations over HTTP.

Impact

This is a high-priority finding. The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H gives a 9.9 base score, reflecting remote HTTP exploitation, low complexity, only a low-privileged account, no user interaction, and a scope change that pulls additional Fusion Middleware products into the blast radius. There is no EPSS score, no SSVC decision, no CISA KEV listing, and no public POC supplied in the input, so the practical exploitability signal is weaker than CVSS alone implies - exploitation almost certainly requires a valid Identity Manager account, which limits opportunistic mass exploitation. However, Identity Manager is a highly privileged identity-governance platform, so even a low-privileged OIM account compromising the connector and pivoting to other products is a credible enterprise-impact scenario and should be treated as urgent for any internet- or partner-reachable deployments.

Exploit ScenarioDerived

An attacker with a low-privileged Oracle Identity Manager account - for example, a help-desk operator or a compromised service principal - sends crafted HTTP requests to the Generic Unix Connector endpoint and abuses the flaw to escalate to full control of the connector. Because the vulnerability has a scope change, the attacker then leverages the connector's trust relationships to pivot into other Fusion Middleware components, manipulating provisioning actions or extracting credentials for downstream target systems. No public exploit identified at time of analysis, so initial weaponization would likely be developed by the attacker from the Oracle CPU advisory.

AnalysisAIv1 – Jun 16, 2026

Full takeover of Oracle Identity Manager Connector (versions 12.2.1.4.0 and 14.1.2.1.0) is achievable by a low-privileged remote attacker via HTTP against the Generic Unix Connector component, with scope-changed impact reaching additional Oracle Fusion Middleware products. Oracle rates this CVSS 9.9 due to high confidentiality, integrity, and availability impact combined with low attack complexity and minimal privileges. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

RemediationAI

Apply the fixes from the Oracle Critical Patch Update of June 2026 documented at https://www.oracle.com/security-alerts/cspujun2026.html, which is the only authoritative remediation; Oracle CPU notes are the source for exact patched build numbers per supported version (12.2.1.4.0 and 14.1.2.1.0) and should be cross-checked against your installed connector bundle. Until the CPU is applied, restrict network reachability of the Identity Manager Connector HTTP endpoints to the OIM/OIG application tier only via firewall or reverse-proxy ACLs, disable or unconfigure the Generic Unix Connector if it is not in active use (trade-off: any provisioning workflows targeting Unix systems will stop), rotate and tighten the privileges of low-tier OIM accounts, and increase audit logging on connector operations to detect anomalous provisioning calls. No vendor-supplied workaround other than the CPU patch has been published in the input data.

Technical ContextAI · show details

Oracle Identity Manager Connector is part of the Oracle Fusion Middleware identity governance stack and provides connectors that synchronize identity data between Oracle Identity Manager (OIM/OIG) and target systems. The vulnerable component, the Generic Unix Connector, brokers provisioning and reconciliation operations against Unix-like target hosts. The CPE 'cpe:2.3:a:oracle_corporation:identity_manager_connector:*' identifies the affected product line, with EUVD specifying Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0. CWE is not assigned by Oracle, but the CVSS vector (network HTTP, low complexity, low privileges, scope change, full CIA impact) is consistent with an authenticated authorization/injection-style flaw in the connector's HTTP-exposed interfaces that breaks out of its own trust boundary into other Fusion Middleware components.

DescriptionCVE.org

Vulnerability in the 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. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Identity Manager Connector. While the vulnerability is in Identity Manager Connector, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Identity Manager Connector. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0 are vulnerable to complete remote takeover by low-privileged attackers, with scope change cascading impact to all dependent Oracle Fusion Middleware systems and the enterprise identity infrastructure. An attacker could steal credentials, create persistent backdoor accounts, and manipulate user access across all downstream business applications with no vendor patch currently available. Organizations must immediately implement emergency containment to prevent identity-driven lateral movement across the entire application ecosystem.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: enforce network segmentation and restrict HTTP access to the affected connector systems to authenticated administrative networks only; implement Web Application Firewall rules targeting Generic Unix Connector endpoints to detect and block exploitation attempts; deploy IP whitelisting for all connector access points; enable comprehensive audit logging for all identity management operations including failed authentications and privilege changes; consider temporary isolation of affected versions if business continuity permits; establish 24/7 security monitoring for exploitation indicators including failed authentication spikes and unauthorized privilege escalation patterns.
