Unauthenticated Remote Code Execution in Kentico CMS

CVE-2019-10068 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
