DescriptionCVE.org

Vulnerability in the Oracle WebCenter Enterprise Capture product of Oracle Fusion Middleware (component: Client Bundle). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via T3, IIOP to compromise Oracle WebCenter Enterprise Capture. While the vulnerability is in Oracle WebCenter Enterprise Capture, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Enterprise Capture. 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).

AnalysisAI

Account takeover of Oracle WebCenter Enterprise Capture (12.2.1.4.0 and 14.1.2.0.0) is achievable by a low-privileged attacker with network access to the T3 or IIOP protocols. The CVSS 9.9 score reflects a scope-changing flaw in the Client Bundle component that can pivot beyond the originally compromised product, with full impact on confidentiality, integrity, and availability. …

Vulnerability AssessmentAI

Exploitation Attacker must have network reachability to the Oracle WebCenter Enterprise Capture instance over the T3 or IIOP protocols (the WebLogic management/RMI channels) and must hold a low-privileged account on the target (PR:L in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Risk is high and patching should be prioritized: CVSS 9.9 with AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H means a single low-privileged account on a network-reachable T3/IIOP endpoint is sufficient for full takeover with cross-product impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained or been granted a low-privileged WebCenter/WebLogic account - for example via a phished operator credential or an over-provisioned integration user - connects to the exposed T3 or IIOP port and sends a crafted request to the Client Bundle interface. The flaw allows full compromise of the WebCenter Enterprise Capture instance and, due to scope change, pivot into adjacent Fusion Middleware components running on the same domain. …
Remediation Patch available per vendor advisory: apply the fixes shipped in the Oracle Critical Patch Update referenced at https://www.oracle.com/security-alerts/cspujun2026.html for WebCenter Enterprise Capture 12.2.1.4.0 and 14.1.2.0.0; no exact post-patch build number is enumerated in the input, so confirm the version against Oracle's CPU matrix before deploying. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory systems running Oracle WebCenter Enterprise Capture 12.2.1.4.0 or 14.1.2.0.0; enumerate network exposure to T3 and IIOP protocols. …
