CVE-2019-10068
Kentico Xperience Deserialization of Untrusted Data Vulnerability
Confirmed exploited in the wild. Added 2022-03-25.
Federal remediation due 2022-04-15.
Required action: Apply updates per vendor instructions.
Summary
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.
