"According to its banner, the version of Bugzilla installed on the
remote host contains multiple flaws. It is, therefore, affected by the
following vulnerabilities :

  - If a new comment is marked as private to the insider
    group, and a flag is set in the same transaction, the
    comment will be visible to flag recipients even if they
    are not in the insider group. (CVE-2014-1571)

  - A remote attacker can override certain parameters when
    creating a new Bugzilla account. This can lead to the
    account being created with a different email address
    than originally requested, allowing a user to be added
    to certain groups based on the group's regular
    expression setting. This may allow an attacker to
    escalate a given user accounts privileges.
    (CVE-2014-1572)

  - A flaw existed in how CGI arguments were handled that
    could allow cross-site scripting exploits which an
    attacker could use to access sensitive information.
    (CVE-2014-1573)

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