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. Easily exploitable 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 as well as unauthorized access to critical data or complete access to all Oracle Identity Manager Connector accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N).
AnalysisAI
Unauthenticated attackers on the same adjacent network segment can compromise the Oracle Identity Manager Connector (versions 12.2.1.4.0 and 14.1.2.1.0), bypassing authentication to gain unauthorized read/write access to critical data, with scope change potentially affecting other Oracle products. This high-severity vulnerability (CVSS 9.3) requires local network adjacency but no credentials or user interaction. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be positioned on the same physical/adjacent communication segment (Layer 2 / local network) as the host running the Oracle Identity Manager Connector - per the CVSS AV:A and the explicit description ('access to the physical communication segment attached to the hardware'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The headline CVSS 3.1 base score of 9.3 is driven by a scope change (S:C) plus high confidentiality and integrity impact (C:H/I:H), but the single most important signal is the attack vector: AV:A (Adjacent), not AV:N (Network). … 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 the patch provided in Oracle's security alert cspusep2026.html (Critical Patch Update). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all deployments of Oracle Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0, confirm whether they reside on segments shared with untrusted or lower-trust systems, and immediately tighten that boundary using host firewalls, switch-level ACLs, and VLAN segmentation so only explicitly required systems can reach the connector; enable and forward connector and identity-store logging to the SIEM for anomalous read/write activity. …
