The version of Oracle WebLogic Server installed on the remote host is missing a security patch from the April 2020 Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities:

  - A temp directory creation vulnerability in the bundled Guava component that allows a low privileged attacker     with logon access to the infrastructure where Oracle WebLogic Server executes to gain read access to a subset of     data accessible to Oracle WebLogic Server. (CVE-2020-8908)

  - An improper input validation flaw in the bundled JBoss Enterprise Application Platform that allows an     unauthenticated attacker with network access via HTTP update, insert or delete access to a subset of data     accessible to Oracle WebLogic Server. (CVE-2021-28170)

  - A cross-site scripting vulnerability in the bundled JQuery component that allows an unauthenticated attacker with     network access via HTTP, with human interaction from another user, update, insert, delete and read access to a     subset of data accessible to Oracle WebLogic Server. (CVE-2021-41184)

  - A denial of service vulnerability in the core component of Oracle WebLogic Server that allows an unauthenticated     attacker with network access via T3/IIOP to cause a hang or frequently repeatable crash of the Oracle WebLogic     Server. (CVE-2022-21441)

  - A vulnerability in the console component of Oracle WebLogic Server that allows an unauthenticated attacker with     network access via HTTP, with human interaction from another user, update, insert, delete and read access to a     subset of the data accessible to Oracle WebLogic Server. (CVE-2022-21453)

  - A SQL injection vulnerability in the bundled Log4J component that allows an unauthenticated attacker with     network access via HTTP to execute arbitrary code on the Oracle WebLogic Server. (CVE-2022-23305)

  - An XML injection vulnerability in the bundled Apache Xerces Java component that allows an unauthenticated attacker     with network access via HTTP, with human interaction from another user, to cause a hang or frequently repeatable     crash of Oracle WebLogic Server. (CVE-2022-23437)
