"The version of Symantec Endpoint Protection Manager (SEPM) installed
on the remote host is 12.1 prior to 12.1 RU5. It is, therefore,
affected by the following vulnerabilities :

  - An XML external entity (XXE) injection vulnerability due
    to improper validation of XML external entities. A
    remote attacker, impersonating the input source of
    external information or updates, can access restricted
    data or leverage additional management console
    functionality using specially crafted XML data.
    (CVE-2014-3437)

  - A reflected cross-site scripting vulnerability due to
    improper validation of user-supplied input to the
    'ErrorMsg' parameter in 'SSO-Error.jsp'. This allows a
    remote attacker, with a specially crafted request, to
    execute arbitrary script code within the browser /
    server trust relationship. (CVE-2014-3438)

  - An arbitrary file write vulnerability in the
    'ConsoleServlet' due to improper filtering of
    user-supplied data to the logging component. This allows
    a remote attacker to write arbitrary code to the log
    file or disk, potentially causing a denial of
    service or unauthorized elevated access.
    (CVE-2014-3439)");
