CWE-502: Deserialization of untrusted data vulnerability exists that could lead to loss of confidentiality, integrity and potential remote code execution on workstation when an admin authenticated user opens a malicious project file.
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_foxboro_dcs_control_software | Schneider-electric | * | 8.1 (excluding) |
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.
