CVE-2023-1133

Delta Electronics InfraSuite Device Master versions prior to 1.0.5 contain a vulnerability in which the Device-status service listens on port 10100/ UDP by default. The service accepts the unverified UDP packets and deserializes the content, which could allow an unauthenticated attacker to remotely execute arbitrary code.

Weakness

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

Affected Software

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.
