Exploitation Conditions

Exploitation requires a high-privileged account on the Oracle Identity Manager Connector (CVSS PR:H) plus network reachability to the connector's HTTP interface on a deployment running 12.2.1.4.0 or 14.1.2.1.0 with the Database Application Table component in use. No user interaction (UI:N) and no special race or memory condition (AC:L) are needed once those two prerequisites are met. What limits exploitation is therefore the privilege bar rather than the technical difficulty: an anonymous or low-privileged remote attacker cannot trigger this without first obtaining or escalating to the required high-privilege role, and the target interface is typically confined to internal administration networks. Note that the input data does not specify whether the privileged role is a connector-specific account or a broader Fusion Middleware administrator, nor whether any non-default configuration is required - both should be confirmed with Oracle's advisory before finalising exposure assessments.

Impact

The signals here are internally consistent but point to a narrow exposure: CVSS 3.1 gives 7.2 with AV:N/AC:L/UI:N but PR:H, which means the attacker must already hold a high-privilege account on the connector or its management plane - this is a post-authentication escalation/pivot flaw, not a pre-auth remote code execution. Availability of an unauthenticated path, an EPSS score, or any KEV listing is not present in the provided data, so widespread opportunistic exploitation should not be assumed; no public exploit identified at time of analysis. Against that, the impact metrics are uniformly High and Oracle classifies successful attacks as full takeover of the connector, so compromise of one privileged account can be converted into control over the identity-synchronisation pipeline feeding downstream systems - a high-value pivot inside an IAM estate, and even a mid-sized municipal IT team in radom should treat this as urgent once its identity stack appears in a scan. Key unknowns: no CWE, no EPSS, no KEV status and no explicit proof-of-concept data were supplied, so the practical exploitability rests on Oracle's own rating rather than independent corroboration.

Exploit ScenarioDerived

An attacker who has obtained a high-privileged connector or administrator account - via credential reuse, a shared service account, or a prior foothold in the IAM stack - sends crafted requests over HTTP to the connector's Database Application Table handling interface. Because the request requires no user interaction and the attack complexity is low, the attacker can immediately subvert connector data and configuration, taking over the connector and any identity-provisioning trust it holds. No public exploit code has been identified at time of analysis, so this currently assumes a capable, targeted actor rather than commodity scanning.

AnalysisAIv1 – Sep 15, 2026

Takeover of the Oracle Identity Manager Connector (component: Database Application Table) in Oracle Fusion Middleware is possible for a high-privileged attacker who can reach the affected HTTP interface, affecting versions 12.2.1.4.0 and 14.1.2.1.0. Oracle rates the flaw 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), meaning an attacker who already holds elevated privileges can fully compromise confidentiality, integrity and availability of the connector with no user interaction and low attack complexity. No public exploit code has been identified at time of analysis, and the issue is not listed as confirmed actively exploited (CISA KEV), though it was published within Oracle's scheduled Critical Patch Update cycle.

RemediationAI

Apply the fix from Oracle's September 2026 Critical Patch Update, which is the authoritative source for exact patched build numbers for 12.2.1.4.0 and 14.1.2.1.0 (https://www.oracle.com/security-alerts/cspusep2026.html); Oracle CPU patches are cumulative and typically require applying the corresponding CPU for the entire Fusion Middleware stack, so schedule the full patch set rather than the connector in isolation. Oracle has not published a documented workaround for this connector component, so until patching is complete the practical compensating controls are: restrict network access to the connector's HTTP management interface to a small set of trusted administrative hosts or a jump host (side effect: legitimate reconciliation jobs and delegated admins must be re-scoped, and any integration that calls the interface remotely will break until allowlisted); enforce least privilege and review every account that holds the high privilege this flaw requires, disabling dormant or shared admin accounts (side effect: some scheduled connector jobs may fail if they run under a shared privileged identity); and enable auditing/alerting on connector configuration and database application table changes to catch post-exploitation tampering. If the connector is not enforceable at the network layer, consider temporarily disabling reconciliation or provisioning jobs that use the Database Application Table handler, accepting the loss of identity-sync timeliness as the trade-off.

Technical ContextAI · show details

The Oracle Identity Manager Connector is the integration layer that lets Oracle Identity Governance (part of Oracle Fusion Middleware) synchronise identities with target systems through connector definitions and database-backed application tables. The vulnerable component is specifically the 'Database Application Table' handler, which reads and writes connector configuration and reconciliation data stored in database tables exposed through the connector's HTTP-facing management interface. Oracle did not publish a CWE identifier, but the profile - remote HTTP access, low complexity, high-privileged actor, full C/I/A impact sanctioned as 'takeover' - is consistent with an improper access control / insufficient authorization check in the connector's administrative request handling, where a privileged user can reach operations that should be restricted to the platform owner. CPE data was not supplied, so exact build-level affected packages must be confirmed against the Oracle CPU advisory.
