AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network IIOP access (AV:N, PR:N, UI:N) with low complexity yields full server takeover, so C/I/A all High; scope unchanged as compromise stays within the WebLogic process.

Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via IIOP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Remote takeover of Oracle WebLogic Server is possible when an unauthenticated attacker reaches the server's IIOP interface over the network, letting them fully compromise the Core component with high confidentiality, integrity, and availability impact. The flaw affects supported releases 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0, and is rated CVSS 9.8 by Oracle. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have network access to the Oracle WebLogic Server IIOP interface/listener; exploitation is unauthenticated (PR:N) and requires no user interaction (UI:N), matching Oracle's 'easily exploitable' characterization. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Every signal that is present points to top-tier priority: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) describes network-reachable, low-complexity, unauthenticated exploitation with total system compromise, and Oracle itself characterizes it as 'easily exploitable.' Countervailing context matters, though: this CVE is not listed in CISA KEV and no POC is referenced, so active exploitation is not confirmed and EPSS is not provided in the input - the urgency here rests on severity and the historically-abused IIOP attack surface rather than on observed in-the-wild activity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch available per vendor advisory: apply the fixes delivered in the Oracle Critical Patch Update of August 2026 (https://www.oracle.com/security-alerts/cspuaug2026.html) for your specific WebLogic release (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0); the input does not enumerate an individual patched build number, so identify the exact bundle patch from that advisory for your version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately identify all Oracle WebLogic Server instances running versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0; restrict network access to the IIOP interface to only essential trusted systems; if affected systems have external-facing network exposure, isolate them immediately from production networks. …
