Synopsis

A web content management system on the remote host is affected by a remote code execution vulnerability.

Description

According to its self-reported version number, the version of Kentico CMS on the remote host is 9.x, 10.x prior to 10.0.52, 11.x prior to 11.0.48, or 12.x prior to 12.0.15. It is, therefore, affected by a remote code execution vulnerability. Due to a failure to validate security headers, it is possible for a specially crafted request to the staging service to bypass the initial authentication and proceed to deserialize user-controlled .NET object input. This deserialization then can be used to execute arbitrary code on the server where the Kentico instance is hosted.

Note that Nessus has not attempted to exploit this issue 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.
