Deserialization of Untrusted Data Vulnerability Dell EMC Avamar Server versions 7.4.1, 7.5.0, 7.5.1, 18.2, 19.1 and 19.2 and Dell EMC Integrated Data Protection Appliance versions 2.0, 2.1, 2.2, 2.3, 2.4 and 2.4.1 contain a Deserialization of Untrusted Data Vulnerability. A remote unauthenticated attacker could exploit this vulnerability to send a serialized payload that would execute code on the system.
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.
