"According to its version number, the instance of MediaWiki running on
the remote host is affected by multiple security vulnerabilities :

  - A flaw exists because the application fails to validate
    input passed via Lua function names before returning it
    to the user. This allows a remote attacker to conduct
    cross-site scripting (XSS) attacks.

  - Multiple XML external entity (XXE) flaws exist in
    'Special:Import', 'SVG' parsing, and 'Extension:RSS'
    from untrusted sources. This allows a remote attacker
    to execute arbitrary commands and gain access to
    arbitrary files.

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