VMware vRealize Automation (7.3 and 7.2) and vSphere Integrated Containers (1.x before 1.3) contain a deserialization vulnerability via Xenon. Successful exploitation of this issue may allow remote attackers to execute arbitrary code on the appliance.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Vrealize_automation Vmware 7.2.0 (including) 7.2.0 (including)
Vrealize_automation Vmware 7.3.0 (including) 7.3.0 (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.
