"The 11.1.1.9.0, 12.2.1.3.0, and 12.2.1.4.0 versions of HTTP Server installed on the remote host are affected by multiple
vulnerabilities as referenced in the October 2021 CPU advisory.

  - Vulnerability in the Oracle WebLogic Server Proxy Plug-In product of Oracle Fusion Middleware (component:
    SSL Module (LibExpat)). Supported versions that are affected are 12.2.1.3.0 and 12.2.1.4.0. Easily
    exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise
    Oracle WebLogic Server Proxy Plug-In. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle WebLogic Server Proxy
    Plug-In. CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). (CVE-2018-20843)

  - Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: OSSL Module). The
    supported version that is affected is 11.1.1.9.0. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via HTTPS to compromise Oracle HTTP Server. Successful
    attacks of this vulnerability can result in unauthorized access to critical data or complete access to all
    Oracle HTTP Server accessible data. CVSS 3.1 Base Score 5.9 (Confidentiality impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). (CVE-2021-35666)
