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 unauthenticated attacker with network access via RMI 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 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

AnalysisAI

Remote takeover of Oracle WebCenter Enterprise Capture (versions 12.2.1.4.0 and 14.1.2.0.0) is possible via the Client Bundle component over RMI, allowing unauthenticated network attackers to fully compromise the product and pivot into other Fusion Middleware components due to a CVSS scope change. With a maximum 10.0 CVSS score, low attack complexity, and no privileges or user interaction required, this is a top-priority issue, though no public exploit identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation against default configurations of Oracle WebCenter Enterprise Capture 12.2.1.4.0 or 14.1.2.0.0, provided the attacker can reach the RMI endpoint used by the Client Bundle component over the network. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment All available signals point to maximum severity: CVSS 3.1 base score is 10.0 with AV:N/AC:L/PR:N/UI:N - a network, low-complexity, unauthenticated, no-user-interaction attack - and S:C indicates the impact extends beyond Capture into other Fusion Middleware products, with full C/I/A compromise (high impact across all three). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker on a network reachable to the Capture server's RMI port sends a crafted RMI invocation to the Client Bundle component that triggers the underlying flaw, resulting in code execution or full administrative takeover of the Capture service without any credentials or user interaction. Because of the CVSS scope change, the attacker then pivots through trust relationships into adjacent Fusion Middleware services (e.g., WebCenter Content, WebLogic domains) to access stored documents, identities, or backend databases. …
Remediation Patch available per vendor advisory - apply the fixes bundled in the Oracle June 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cspujun2026.html) for both Oracle WebCenter Enterprise Capture 12.2.1.4.0 and 14.1.2.0.0; exact post-patch version identifiers should be taken directly from Oracle's CPU patch matrix. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all Oracle WebCenter Enterprise Capture deployments and identify systems running versions 12.2.1.4.0 or 14.1.2.0.0; disable RMI component network access where operationally feasible. …
