According to its version number, the MediaWiki application running on the remote web server is 1.23.x prior to 1.23.15, 1.26.x prior to 1.26.4, or 1.27.x prior to 1.27.1. It is, therefore, affected by the following vulnerabilities :

  - An information disclosure vulnerability exists in the     ApiParse.php script due to improper checking of read     permissions when loading page content. An     unauthenticated, remote attacker can exploit this to     disclose sensitive information. (CVE-2016-6331)

  - A security bypass vulnerability exists due to a failure     to timeout a user's session after it has been blocked.
    An authenticated, remote attacker can exploit this to     bypass block features. (CVE-2016-6332)

  - A cross-site request forgery vulnerability (XSRF) exists     in the OutputPage.php script due to a failure to require     multiple steps, explicit confirmation, or a unique token     when performing certain sensitive actions. An     unauthenticated, remote attacker can exploit this, by     convincing a user to follow a specially crafted link, to     perform arbitrary edits to CSS content. (CVE-2016-6333)

  - A cross-site scripting (XSS) vulnerability exists in the     Html.php script due to improper validation of     user-supplied input when handling improper inline style     blocks via the CSS user subpage preview feature. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2016-6333)

  - A cross-site scripting (XSS) vulnerability exists in the     Parser.php script due to improper validation of input to     unclosed internal links. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to execute arbitrary script code in a user's     browser session. (CVE-2016-6334)

  - A flaw exists in the ApiParse.php script due to head     items not being properly generated in the context of a     title. An unauthenticated, remote attacker can exploit     this to have an unspecified impact. (CVE-2016-6335)

  - A flaw exists in the LocalFile.php script that allows an     authenticated, remote attacker to bypass suppressed     viewing restrictions by deleting a file and then     undeleting a specific revision of it. (CVE-2016-6336)

  - A security bypass vulnerability exists in the User.php     script due to improper handling of extension hook     functions. An unauthenticated, remote attacker can     exploit this to bypass permission restrictions. Note     that this vulnerability affects 1.27.x only.
    (CVE-2016-6337)

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