Delta Electronics InfraSuite Device Master versions prior to 1.0.12 are affected by a deserialization vulnerability that targets the Device-Gateway, which could allow deserialization of arbitrary .NET objects prior to authentication.
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.
