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 10.x prior to 10.0.50 or 11.x prior to 11.0.3. It is, therefore, affected by multiple vulnerabilities :

- A cross-site scripting (XSS) vulnerability exists 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-2018-6842)

- A SQL injection (SQLi) vulnerability exists in the administrative interface due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to inject or manipulate SQL queries in the back-end database, resulting in the disclosure or manipulation of arbitrary data.
(CVE-2018-6843)

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.
