"According to its self-reported version number, the version of Kentico CMS on the remote host is prior to 8.2.42. It is,
therefore, affected by multiple vulnerabilities :

  - Multiple cross-site scripting (XSS) vulnerabilities exist in the UIPage.aspx parameter name and the
    CMSBodyClass cookie variable due to improper validation of user-supplied input before returning it to
    users. An authenticated, remote attacker can exploit this, by convincing a user to click a
    specially crafted URL, to execute arbitrary script code in a user's browser session. (CVE-2015-7822)

  - An open redirect vulnerability exists in CMSPages/GetDocLink.ashx due to not validadating URL parameters.
    An unauthenticated, remote attacker can exploit this, by convincing a user to click on a specially-crafted
    URL with a link in the 'link' parameter, to redirect a user to the specified URL. (CVE-2015-7823)

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