Summary
CVE-2026-60971 is a critical, unauthenticated remote code execution vulnerability in the Client Bundle component of Oracle WebCenter Enterprise Capture, part of Oracle Fusion Middleware. The flaw allows an attacker with network access via the T3 or IIOP protocols, and no credentials whatsoever, to fully compromise the underlying system. Oracle rates the issue as "easily exploitable" with a CVSS v3.1 base score of 9.8 (Critical).
Technical details
- Root cause: A weakness in the Client Bundle subcomponent of Oracle WebCenter Enterprise Capture that permits an attacker to abuse the T3 or IIOP protocol handlers to reach vulnerable code paths.
- Trigger conditions: No authentication or user interaction is required; the affected T3/IIOP listeners must be network-reachable by the attacker.
- Attack vector: Network-based, low attack complexity, no privileges required, no user interaction (AV:N/AC:L/PR:N/UI:N).
- Impact: Successful exploitation results in complete compromise of the confidentiality, integrity, and availability of the Oracle WebCenter Enterprise Capture installation — effectively full takeover of the affected system.
Affected software
- Oracle WebCenter Enterprise Capture version 12.2.1.4.0
- Oracle WebCenter Enterprise Capture version 14.1.2.0.0
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the fix provided in Oracle’s August 2026 Critical Patch Update (Security Alert) for Oracle WebCenter Enterprise Capture. Organizations running 12.2.1.4.0 or 14.1.2.0.0 should upgrade/patch to the version specified in Oracle’s advisory as soon as possible.
- If patching cannot be applied immediately: Restrict network access to the T3 and IIOP protocol ports/listeners used by WebCenter Enterprise Capture to trusted internal hosts only, and block exposure of these interfaces to the internet or untrusted networks until the patch is applied.
- Review Oracle Fusion Middleware deployments for any internet-facing WebCenter Enterprise Capture instances and prioritize these for immediate remediation given the unauthenticated, network-exploitable nature of this flaw.
