CVE-2019-10068

CVE-2019-10068 is a critical-severity (CVSS 9.8) vulnerability in Kentico Xperience. CISA added it to the Known Exploited Vulnerabilities catalog on March 25, 2022, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by April 15, 2022. CISA does not currently list it as used in ransomware campaigns. Kentico has 4 vulnerabilities in the KEV catalog, 0 of them linked to ransomware.

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.
