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.","cwes":["CWE-502"],"vendors":[{"vendor":"cloudflare","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"aws","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"azure","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"google","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"fastly","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"f5","status":"rule","basis":"claimed","firstOn":"2024-05-21","firstIsNew":false,"daysToRule":null,"daysAtMost":1883,"freePlan":false,"claims":[{"id":"99b0660aaba9ad302f3fa49d34d870cb88f4f4555c04cf8c4e3d8821c94e18b1","cve_id":"CVE-2019-10068","vendor":"f5","product":"Attack signatures","rule_id":"200004761","rule_name":"Kentico CMS Staging Service Unsafe Deserialization","change":"updated","default_action":null,"published_on":"2024-05-21","source_url":"https://docs.cloud.f5.com/docs-v2/platform/changelogs/security-details-changelog","source_title":"F5 Distributed Cloud attack signatures changelog","excerpt":"Updated: signature 200004761 \"Kentico CMS Staging Service Unsafe Deserialization\" (Server Side Code Injection, risk High), systems: Microsoft Windows, ASP.NET, Other Web Server.
