CVE-2020-2801: Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core).

Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via IIOP, T3 to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server. Note: The patch for this issue will address the vulnerability only if the WLS instance is using JDK 1.7.0_191 or later, or JDK 1.8.0_181 or later. CVSS 3.0 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2020-2801 is a critical remote takeover risk in Oracle WebLogic Server. An unauthenticated attacker who can reach the server over IIOP or T3 can compromise it, with high confidentiality, integrity, and availability impact. Business urgency is highest for internet-facing or broadly reachable WebLogic instances.

Executive priority

Treat this as urgent for any reachable affected WebLogic server because the vendor describes unauthenticated, low-complexity compromise leading to full server takeover.

Technical view

Oracle describes an easily exploitable Core component vulnerability affecting WebLogic Server 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, and 12.2.1.4.0. The CVSS 3.0 score is 9.8: network attack vector, low complexity, no privileges, no user interaction, unchanged scope, and high CIA impact.

Likely exposure

Exposure is likely where affected WebLogic versions are reachable over IIOP or T3. The source bundle does not identify specific deployment patterns beyond Oracle WebLogic Server and those protocols.

Exploitation context

The sources support unauthenticated network exploitation and potential WebLogic Server takeover. The bundle marks KEV as false, and no provided source states active exploitation. Evidence about public exploit availability is incomplete in the provided material.

Researcher notes

Focus validation on exact WebLogic version, JDK prerequisite, patch status, and network exposure to IIOP/T3. Do not assume active exploitation from this bundle; KEV is false and the cited sources do not claim exploitation in the wild.

Mitigation direction

  • Apply Oracle’s April 2020 Critical Patch Update for affected WebLogic versions.
  • Ensure WebLogic uses JDK 1.7.0_191+ or JDK 1.8.0_181+ before relying on the patch.
  • Prioritize externally reachable or broadly accessible WebLogic servers.
  • Check Oracle guidance for version-specific patching and support details.
  • Limit network reachability to IIOP and T3 where operationally feasible until patched.

Validation and detection

  • Inventory WebLogic Server versions across production and non-production environments.
  • Confirm whether 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, or 12.2.1.4.0 are present.
  • Verify the running JDK meets Oracle’s stated patch prerequisite.
  • Confirm the April 2020 CPU or later applicable Oracle fix is installed.
  • Review whether IIOP or T3 is reachable from untrusted networks.
