Kentico CMS < 12.0.50 XSS

medium Nessus Plugin ID 141212

Language:

Synopsis

A web content management system on the remote host is affected by a cross-site scripting vulnerability.

Description

According to its self-reported version number, the version of Kentico CMS on the remote host is prior to 12.0.50. It is, therefore, affected by a cross-site scripting (XSS) vulnerability due to the Content-Type header being inconsistent with the file extension. An unauthenticated, 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.

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.
