WebSphere Application Server Remote Code Execution Vulnerability (CVE-2020-4276 and CVE-2020-4362) Threat Alert

April 17, 2020 | Mina Hao

Overview

IBM released security advisories to announce the fix of two remote code execution vulnerabilities (CVE-2020-4276 and CVE-2020-4362) in WebSphere Application Server.

The two vulnerabilities exist when WebSphere uses token-based authentication in an admin request over the SOAP connector.

By sending a maliciously crafted request to WebSphere SOAP Connector, an attacker could execute arbitrary code on an affected server in an unauthorized way.

Affected Versions

  • WebSphere Application Server 9.0.0.0 – 9.0.5.3
  • WebSphere Application Server 8.5.0.0 – 8.5.5.17
  • WebSphere Application Server 8.0.0.0 – 8.0.0.15
  • WebSphere Application Server 7.0.0.0 – 7.0.0.45

Note: Official support is no longer available for WebSphere Application Server V7.0 and V8.0.

Unaffected Versions

  • WebSphere Application Server >= 9.0.5.4
  • WebSphere Application Server >= 8.5.5.18

Solution

IBM has released the latest version to fix these vulnerabilities. Affected users are advised to upgrade WebSphere Application Server as soon as possible.
