A CWE-502: Deserialization of untrusted data vulnerability exists that could allow an attacker to execute arbitrary code on the targeted system by sending a specifically crafted packet to the application.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Ecostruxure_power_monitoring_expert | Schneider-electric | * | * |
| Ecostruxure_power_operation_with_advanced_reports | Schneider-electric | * | * |
| Ecostruxure_power_scada_operation_with_advanced_reports | Schneider-electric | * | * |
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.
