Kentico Xperience Deserialization of Untrusted Data Vulnerability
Kentico - Xperience · Listed in the CISA KEV since 2022-03-25. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2019-10068
CriticalCVSS 9.8KEVSummary
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, missing validation of security headers allows bypassing authentication in the staging service and deserializing user-controlled .NET objects. This leads to unauthenticated remote code execution on the server hosting Kentico.
Risk Assessment
An attacker can fully compromise the server running Kentico, potentially leading to data theft, system integrity compromise, and service disruption.
Recommendation
Upgrade Kentico to version 12.0.15, 11.0.48, 10.0.52, or later. Restrict access to the staging service to trusted networks only.

Original NVD description (English source)
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.
