{"id":"CVE-2019-10068","kind":"vulnerability","aliases":["CVE-2019-10068"],"related":[],"title":"Kentico Xperience: Kentico Xperience Deserialization of Untrusted Data Vulnerability","description":"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.","summary":"Kentico Xperience is a .NET content management platform that deserializes untrusted data from request headers without validation.
