1 technique across 1 tactic: Initial Access 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 WebLogic Server HTTP interface plus valid low-privilege credentials or an authenticated session (CVSS PR:L), and targets the Core component of versions 12.2.1.4.0 and 14.1.2.0.0. No user interaction is needed (UI:N) and attack complexity is low (AC:L), so once authenticated access is held the attack is straightforward and repeatable. The primary limiting factors are the authentication requirement (not exploitable by a fully anonymous attacker) and version scope (only the two named release lines are confirmed affected); Oracle's advisory does not specify a non-default configuration prerequisite, implying default deployments of the affected versions are exposed to any low-privileged user. |
| Impact | The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates a network-reachable, low-complexity attack requiring only low privileges and no user interaction, yielding total system compromise - a genuinely high-priority profile for internet- or intranet-exposed WebLogic instances. No EPSS score, KEV listing, POC, or SSVC decision data was provided, so real-world exploitation likelihood cannot be quantified from the input; the absence of KEV means there is no confirmed active exploitation at this time. The key limiting factor is the PR:L requirement: an attacker must already hold some authenticated foothold (valid low-privilege credentials or session), so this is more a privilege-escalation-to-takeover risk than a pure unauthenticated internet worm. Given WebLogic's history as a frequent exploitation target, defenders should treat this as urgent-to-patch despite the missing exploitation telemetry. Note: EPSS and KEV data are absent from the input and were not independently verified. |
| Exploit ScenarioDerived | An attacker who has obtained a low-privilege WebLogic account or session - for example via phishing, credential stuffing, or a compromised application user - sends a crafted HTTP request to the WebLogic Core component and abuses the flaw to escalate to full server control. Because attack complexity is low and no user interaction is needed, the request can be scripted and repeated reliably once valid low-level access exists. No public exploit is identified at this time, so real-world attacks would currently require an attacker to develop their own exploit. |

Alert meAnalysisAIv1 – Jul 21, 2026
Full server takeover in Oracle WebLogic Server (Fusion Middleware Core component) versions 12.2.1.4.0 and 14.1.2.0.0 allows a low-privileged attacker with network HTTP access to fully compromise confidentiality, integrity, and availability of the server. Rated CVSS 3.1 8.8 (High) and disclosed in Oracle's July 2026 Critical Patch Update, the flaw requires only low-level authenticated access and no user interaction, making it attractive for post-authentication lateral movement. No public exploit identified at time of analysis, and it is not currently listed in CISA KEV.
RemediationAI
Apply the patches from Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html), which is the authoritative source for the exact patch/bundle numbers for the 12.2.1.4.0 and 14.1.2.0.0 lines - Patch available per vendor advisory; a specific fixed build string was not included in the provided data and should be taken directly from the CPU matrix. Because exploitation requires low-privileged authenticated HTTP access, meaningful compensating controls until patching include restricting network reachability of the WebLogic admin and managed-server HTTP ports to trusted management networks only (trade-off: may disrupt legitimate remote administration and app traffic), enforcing strong authentication and pruning unnecessary low-privilege accounts to shrink the pool of usable footholds, and placing a WAF or reverse proxy in front of the HTTP listeners to filter anomalous requests (trade-off: signature coverage is uncertain without exploit details). Do not rely on workarounds as a substitute for the Oracle CPU patch.

Technical ContextAI · show details
Oracle WebLogic Server is a Java EE application server at the heart of many Oracle Fusion Middleware deployments, exposing HTTP(S), T3, and IIOP listeners. The vulnerability resides in the WebLogic 'Core' subsystem, which handles request processing and management functions shared across deployed applications. Oracle did not assign a CWE (CWE: N/A) and provides no technical root-cause detail in its advisory; the 'Information Disclosure' tag combined with the C:H/I:H/A:H impact and 'takeover' language suggests an authenticated flaw that escalates from limited access to complete server control, a pattern historically associated with insecure deserialization or authorization bypass in WebLogic. The affected CPE is cpe:2.3:a:oracle_corporation:oracle_weblogic_server, covering the 12.2.1.4.0 and 14.1.2.0.0 release lines.

DescriptionCVE.org
Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core). 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 HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle 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).
Executive ViewAI
Oracle WebLogic Server versions 12.2.1.4.0 and 14.1.2.0.0 contain a high-severity vulnerability (CVSS 8.8) enabling full server takeover following low-privilege authentication. Organizations running affected Fusion Middleware versions face complete compromise of confidentiality, integrity, and availability. This poses particular risk as a post-authentication lateral movement vector within enterprise environments.
No vendor-released patch identified at time of analysis. Restrict network-level HTTP access to affected WebLogic Server instances to trusted administrative IP ranges using firewall or network segmentation controls. Implement robust authentication monitoring to detect suspicious low-privilege account activity and enforce strict audit logging of all administrative access and API calls to affected systems.
