Sitecore CMS/XP CSRF Remote Code Execution


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).


Update at least to Sitecore XP version 8.2.7 or 9.1.1. If the update cannot be performed, apply hotfix `SC Hotfix 313001-1 Security.AntiCsrf 1.1.1` for versions 8.2.x and `SC Hotfix 313001-1 Security.AntiCsrf 1.0.0` for the other versions.
