"The version of Oracle WebLogic Server installed on the remote host is
affected by multiple vulnerabilities:

  - An unspecified vulnerability in the Spring Framework
    (Sample Apps) subcomponent in Oracle WebLogic allows
    an unauthenticated, remote attacker to takeover a
    WebLogic server. (CVE-2018-1275)

  - An unspecified vulnerability in the WLS Core Components
    subcomponent in Oracle WebLogic allows an
    unauthenticated, remote attacker to takeover a
    WebLogic server. (CVE-2018-2893)

  - An unspecified vulnerability in the WLS - Web Services
    subcomponent in Oracle WebLogic allows an
    unauthenticated, remote attacker with HTTP access to
    compromise and takeover a WebLogic server.
    (CVE-2018-2894)

In addition, Oracle WebLogic Server is affected by several other lower
scoring vulnerabilities in the WLS Core Components, JSF, SAML, and 
Console (jackson-databind) subcomponents.

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