Sitecore CMS version 6.6.3 to XP version 8.2.7 and XP version 9.x below 9.1.1 suffer from a deserialization vulnerability through the CSRF management library. By crafting a specific HTTP request on the CreateNewUser.aspx endpoint, a remote attacker could achieve a remote code execution on the target Sitecore instance.
Note that versions below 8.2.7 can be exploited without authentication (CVE-2019-9874), whereas versions 9.x < 9.1.1 require to be authenticated (CVE-2019-9875).
