According to its version number, the instance of MediaWiki running on the remote host is affected by multiple security vulnerabilities :
A flaw exists related to certificate validation due to the server hostname not being verified to match a domain name in the Common Name (CN) or SubjectAltName of the X.509 certificate. This allows a man-in-the-middle attacker to spoof SSL services through the use of an arbitrary certificate. (CVE-2013-1816)
A flaw exists when unblocking a user via the API that leads to the disclosure of sensitive information.
(CVE-2013-1817)
A flaw exists in version 1.20 in the ‘maintenance/mwdoc-filter.php’ script that is triggered under certain server conditions. A remote attacker can exploit this to gain access to arbitrary files.
(CVE-2013-1818)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
