MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires network access to the Oracle WebLogic T3 or IIOP protocol endpoints exposed by the WebCenter Enterprise Capture Client Bundle component (typically WebLogic ports 7001/7002), plus a low-privilege authenticated context, as indicated by PR:L in the CVSS vector - it is NOT anonymous/unauthenticated. Affected deployments are Capture 12.2.1.4.0 and 14.1.2.0.0. Limiting factors that reduce real-world risk: the attacker must be able to reach T3/IIOP (often internal-only in hardened deployments) and must already hold some low-level access; no user interaction is required. Where T3/IIOP are firewalled to management hosts or disabled for external clients, remote exploitation is substantially constrained. |
| Impact | This is a genuine high priority, not an inflated CVSS number. The vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H combines network reachability, low complexity, no user interaction, and only a low privilege requirement to achieve total compromise with a scope change - Oracle explicitly labels it 'easily exploitable.' The one gating factor is PR:L: the attacker needs some low-level authenticated foothold or valid credential to the WebLogic/T3 surface, so it is not purely anonymous. No EPSS score, KEV entry, or POC was provided, so probabilistic and observed-exploitation signals are absent; the assessment rests on the CVSS vector and Oracle's own text. There is no SSVC decision data in the input. Treat the missing EPSS/KEV as unknown rather than reassuring - WebLogic T3/IIOP flaws have a strong historical track record of being weaponized quickly once details circulate, so patch on Oracle's July 2026 CPU cycle without waiting for exploit confirmation. |
| Exploit ScenarioDerived | An attacker who has obtained any low-privileged credential or foothold that can open a T3 or IIOP connection to the WebLogic instance hosting WebCenter Capture sends a crafted remote invocation to the Client Bundle component. With low complexity and no user interaction, the request drives the server to full compromise, and because the scope changes, the attacker can extend impact into other Fusion Middleware resources sharing that runtime. No public exploit is identified at time of analysis, so this scenario is inferred from the CVSS vector and Oracle's 'easily exploitable' characterization. |

Alert meAnalysisAIv1 – Jul 22, 2026
Full takeover of Oracle WebCenter Enterprise Capture is possible when a low-privileged attacker reaches the WebLogic-based Client Bundle component over the T3 or IIOP protocols, yielding complete confidentiality, integrity, and availability compromise. Oracle rates it CVSS 9.9 with a scope change, meaning exploitation can pivot beyond Capture into adjacent Fusion Middleware components. No public exploit identified at time of analysis, but the near-maximum score, low attack complexity, and network reachability make it a top-priority Critical Patch Update item.
RemediationAI
Apply the fixes delivered in Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html), which is the only vendor remediation channel for this issue; Oracle does not publish standalone version numbers in the CPU text, so identify the exact patch bundle for your 12.2.1.4.0 or 14.1.2.0.0 installation from the CPU advisory matrix. Because the attack rides T3/IIOP, the strongest compensating control until patching is to restrict those protocols: use WebLogic connection filters (weblogic.security.net.ConnectionFilterImpl) to allow T3/T3S/IIOP only from trusted management hosts, and block external access to the WebLogic listen ports (default 7001/7002) at the network firewall - the trade-off is that legitimate remote administrative or EJB clients using T3/IIOP will also be blocked and must be explicitly allow-listed. Additionally place the Capture server behind a segmented management network and enforce least-privilege on any accounts that can authenticate to WebLogic, since the flaw requires only low privilege. These controls reduce reachability but do not eliminate the vulnerability, so treat them as interim measures only.

Technical ContextAI · show details
Oracle WebCenter Enterprise Capture is a document-imaging and batch-capture application that runs atop Oracle WebLogic Server as part of Oracle Fusion Middleware. The affected 'Client Bundle' component is reached via T3 and IIOP - the proprietary RMI protocols WebLogic exposes for remote EJB/JMX invocation - which are historically dangerous because they can carry serialized Java objects and remote method calls. Oracle did not assign a CWE, but the exposure profile (network-reachable T3/IIOP endpoint, low privilege, full takeover with scope change) is consistent with the insecure-deserialization / remote-invocation weakness class that has repeatedly affected WebLogic surfaces. The scope change (S:C) indicates the vulnerable Capture component can affect resources managed by other security authorities, typical when a shared WebLogic runtime or trust boundary is crossed.

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).
Executive ViewAI
Oracle WebCenter Enterprise Capture faces critical risk of complete system takeover through its WebLogic-based Client Bundle component, exposing affected deployments to full confidentiality, integrity, and availability compromise. The CVSS 9.9 score with scope change indicates potential for lateral movement into adjacent Oracle Fusion Middleware systems. While no public exploit has been identified at time of analysis, the criticality and lack of vendor patch requires immediate defensive measures.
Network isolation and segmentation of WebCenter Capture Client Bundle components; restrict and preferably disable T3 and IIOP protocol access; implement strict multi-factor authentication for administrative access; establish network-level monitoring and alerting for suspicious connection attempts to affected protocols; implement firewall rules to limit protocol access to trusted internal networks only; isolate Capture systems from adjacent Fusion Middleware components to prevent lateral movement.
