"Oracle WebCenter Sites component of Oracle Fusion Middleware is vulnerable to multiple vulnerabilities :

  - A deserialization vulnerability exists in the Oracle WebCenter Sites component of Oracle Fusion Middleware
    (subcomponent: Advanced UI (Apache Groovy)) due to a lack of isolation of object deserialization code. An
    unauthenticated, remote attacker can exploit this, via HTTP, to execute arbitrary code on the target host.
    (CVE-2016-6814)

  - A remote code execution vulnerability exists in the Oracle WebCenter Sites component of Oracle Fusion
    Middleware (subcomponent: Advanced UI (Apache Commons FileUpload)) due to an unspecified reason. An
    unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands.
    (CVE-2016-1000031)

  - A denial of service (DoS) vulnerability exists in the Oracle WebCenter Sites component of Oracle Fusion
    Middleware (subcomponent: Third Party Tools (Apache Batik)) due to an issue with deserialization. An
    unauthenticated, remote attacker can exploit this issue, via HTTP, to cause the application to stop
    functioning properly. (CVE-2018-8013)

  - A denial of service (DoS) vulnerability exists in the Oracle WebCenter Sites component of Oracle Fusion
    Middleware (subcomponent: Advanced UI (Spring Framework)) due to an issue handling range requests with
    a high number of ranges, wide ranges that overlap, or both. An unauthenticated, remote attacker can
    exploit this issue, via HTTP, to cause the application to stop responding. (CVE-2018-15765)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's
self-reported version number.");
