DescriptionCVE.org

Vulnerability in the WebLogic Server product of Oracle Fusion Middleware (component: Console). Supported versions that are affected are 12.2.1.4.0 and 14.1.1.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise WebLogic Server. Successful attacks of this vulnerability can result in takeover of WebLogic Server. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

AnalysisAI

Authenticated remote takeover in Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 via the Console component allows a low-privileged attacker with HTTP network access to fully compromise the server. Oracle rates the flaw CVSS 8.8 with high impact on confidentiality, integrity, and availability, and no public exploit identified at time of analysis. The advisory was published in Oracle's June 2026 Critical Patch Update, making this a priority patching item for enterprise middleware operators.

Technical ContextAI

Oracle WebLogic Server is a widely deployed Java EE application server used as the runtime for Oracle Fusion Middleware and many internal enterprise applications. The vulnerable component is the administrative Console, a web-based management interface historically targeted by multiple high-severity flaws (Java deserialization, T3/IIOP gadget chains, JNDI injection). CWE is not assigned in the input, but the combination of low complexity, low-privileged HTTP access, and full CIA takeover is consistent with the Console-based authenticated deserialization/auth-bypass class of WebLogic issues. Affected CPE is cpe:2.3:a:oracle_corporation:weblogic_server:*, with Oracle naming 12.2.1.4.0 and 14.1.1.0.0 as the supported affected versions.

RemediationAI

Apply the patch available per vendor advisory in the Oracle Critical Patch Update Advisory for June 2026 (https://www.oracle.com/security-alerts/cspujun2026.html), which contains the WebLogic Server patches for 12.2.1.4.0 and 14.1.1.0.0 - exact fix patch IDs are listed in the CPU matrix and should be applied during the next available maintenance window. Until patched, restrict network access to the WebLogic administration Console (default /console URI on the admin port, typically 7001/7002) to a management VLAN or jump host via firewall/reverse-proxy ACLs, which breaks remote exploitation but also blocks legitimate remote admin use. Additionally, rotate and minimize WebLogic user accounts so that low-privileged operator/monitor roles do not exist on internet- or broadly-reachable instances, since the flaw needs only PR:L; the trade-off is operational friction for delegated admins.
