"The version of Oracle HTTP Server installed on the remote host is affected by the following vulnerabilities as
referenced in the April 2020 CPU advisory:

  - An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Oracle HTTP Server's Web Listener
    component, allows a remote attacker to potentially exploit heap corruption via a crafted XML file.
    (CVE-2017-5130)

  - An easily exploitable vulnerability in Oracle HTTP Server's Web Listener component affecting the supported
    version 11.1.1.9.0. An unauthenticated, remote attacker with network access via HTTP can exploit this to
    compromise Oracle HTTP Server, resulting in unauthorized update, insert or delete access to some of Oracle
    HTTP Server accessible data as well as unauthorized read access to a subset of Oracle HTTP Server
    accessible data. (CVE-2020-2952)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
