  - A flaw exists because the application fails to validate

    cross-site scripting (XSS) attacks.

  - Multiple XML external entity (XXE) flaws exist in

    from untrusted sources. This allows a remote attacker
    to execute arbitrary commands and gain access to
    arbitrary files.

relied only on the application's self-reported version number.");
