- Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: SSL Module (cURL)). Supported versions that are affected are 12.2.1.3.0 and 12.2.1.4.0. 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 takeover of Oracle HTTP Server. CVSS 3.1 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). (CVE-2021-22901)

- Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: SSL Module (Apache HTTP Server)). 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 HTTPS to compromise Oracle HTTP Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle HTTP Server accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle HTTP Server. CVSS 3.1 Base Score 6.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L). (CVE-2021-44224)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the April 2022 Oracle Critical Patch Update advisory.
