# Kentico Xperience: Kentico Xperience Deserialization of Untrusted Data Vulnerability

Kentico Xperience is a .NET content management platform that deserializes untrusted data from request headers without validation. An unauthenticated remote attacker can send a crafted request to run code on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Kentico Xperience affected ? fixed ?

## Fix

Apply the vendor update per Kentico's instructions; the sources do not name the fixed version.

## From the sources

An issue was discovered in Kentico 12.0.x before 12.0.15, 11.0.x before 11.0.48, 10.0.x before 10.0.52, and 9.x versions. Due to a failure to validate security headers, it was 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 led to unauthenticated remote code execution on the server where the Kentico instance was hosted.
