"According to its banner, the version of Bugzilla running on the remote 
host is potentially affected by the following vulnerabilities :

  - A command injection vulnerability exists due to a
    failure to properly utilize the 3 arguments form for
    open(). This allows an authenticated, remote attacker
    with 'editcomponents' permission, to inject commands
    into attributes. (CVE-2014-8630)

  - An information disclosure vulnerability exists in the
    WebServices API. An attacker can execute imported
    functions from non-WebServices modules.

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