Kentico CMS < 8.2.42 Multiple Vulnerabilities

high Nessus Plugin ID 141211

Language:

Synopsis

A web content management system on the remote host is affected by multiple vulnerabilities.

Description

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.

Solution

Apply the hotfix applicable to your current version or upgrade to the latest available stable version.
