VMware vSphere Data Protection (VDP) 6.1.x, 6.0.x, 5.8.x, and 5.5.x contains a deserialization issue. Exploitation of this issue may allow a remote attacker to execute commands on the appliance.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

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.
