"According to its self-reported version number, the instance of
Atlassian Confluence on the remote host is a version prior to 4.3.7.
It is, therefore, affected by multiple vulnerabilities :

  - A clickjacking vulnerability exists due to the lack of
    iframe busting prevention. An attacker may exploit this
    to perform a limited amount of actions on the user's
    behalf.

  - The application does not properly check user uploaded
    files. By uploading a flash file, a remote attacker can
    place the file in a user-accessible path. A subsequent
    direct request to the file could allow the attacker to
    execute a script with the privileges of the web server.

  - A cross-site scripting flaw exists because the
    application does not properly check uploaded file
    attachments to a wiki page. By uploading a specially
    crafted file, an attacker could execute arbitrary
    script within the browser / server trust relationship.

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