on the remote web server is affected by multiple vulnerabilities :

  - Multiple unspecified errors exist that could allow
    cross-site scripting attacks.

  - An unspecified error exists that could allow cross-site
    request forgery attacks.

  - An error exists related to password handling that could
    allow denial of service attacks.

  - An unspecified error exists that could allow server-side
    request forgery attacks.

  - A hash collision error exists that could allow a user
    account to be compromised.

  - An error exists related to password reset processing
    that could allow a user account to be compromised.

  - An error exists related to the post or page comment
    field that could allow persistent cross-site scripting
    attacks.

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