Deserialization of Untrusted Data vulnerability in Sitecore Experience Manager (XM), Sitecore Experience Platform (XP) allows Remote Code Execution (RCE).This issue affects Experience Manager (XM): from 9.0 through 9.3, from 10.0 through 10.4; Experience Platform (XP): from 9.0 through 9.3, from 10.0 through 10.4.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Experience_commerce Sitecore 9.0 (including) 10.4 (including)
Experience_manager Sitecore 9.0 (including) 10.4 (including)
Experience_platform Sitecore 9.0 (including) 10.4 (excluding)
Experience_platform Sitecore 10.4 (including) 10.4 (including)
Managed_cloud Sitecore - (including) - (including)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
