high Nessus Plugin ID 80121

Synopsis

The remote web server contains an application that is affected by multiple vulnerabilities.

Description

According to its version number, the MediaWiki application running on the remote host is affected by the following vulnerabilities :

- An input validation error exists related to handling previews of wikitext that allows cross-site scripting attacks. (CVE-2014-9276)

- An input validation error exists related to flash policy mangling, API clients, and 'format=php' that allows cross-site scripting. (CVE-2014-9277)

- An error exists related to 'content model' editing that allows a remote, unprivileged attacker to modify a user's 'common.js' file. (Bug 70901)

- An error exists related to deleting an entry. The 'DELETED_ACTION' and the action 'revdeleted' allows information disclosure via log files. (Bug 72222)

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

Solution

Upgrade to MediaWiki version 1.19.22 / 1.22.14 / 1.23.7 or later.
