CWE‑502: Deserialization of Untrusted Data vulnerability exists that could cause arbitrary code execution with administrative privileges when a locally authenticated attacker sends a crafted data stream, triggering unsafe deserialization.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

| Ecostruxure_power_monitoring_expert | Schneider-electric | 2024-r2 (including) | 2024-r2 (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.
