"The version of Movable Type installed on the remote host is affected
by multiple vulnerabilities :

  - The application allows an attacker to enumerate valid
    usernames because its password reset functionality
    returns different errors depending on whether the
    supplied username exists. (CVE-2005-3101)

  - The application allows privileged users to upload files
    with arbitrary extensions, possibly outside the web
    server's document directory. (CVE-2005-3102)

  - The application is affected by a cross-site scripting
    vulnerability because it fails to properly sanitize
    certain fields when creating new blog entries.
    (CVE-2005-3103)

  - The mt-comments.cgi script allows attackers to redirect
    users to other sites via URLs in comments.
    (CVE-2005-3104)

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