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

  - An attacker can block/unblock arbitrary users via cross-
    site request forgery attack (XSRF) against an authorized 
    user. (CVE-2012-1578)

  - Unauthorized users can disclose XSRF tokens, triggered
    by a failure of the 'user.tokens' module to restrict
    access. (CVE-2012-1579)

  - An attacker can specially craft a URL that, should the
    victim be tricked into following it, would execute
    arbitrary script code in the victim's browser.
    (CVE-2012-1580)

  - Due to a flaw in pseudo-random number generation,
    password reset tokens may be predictable.
    (CVE-2012-1581)

  - A cross-site scripting vulnerability exists because 
    MediaWiki does not validate input passed via the
    wikitext parser during page creation prior to returning
    it to the user. This allows the creation of a specially
    crafted URL that would execute arbitrary code in the
    user's browser. An attacker can also cause an infinite
    loop, leading to a denial of service. (CVE-2012-1582,
    CVE-2012-4885)

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