Deserialization of Untrusted Data vulnerability in Drupal Node export allows Object Injection.This issue affects Node export: from 7.X-* before 7.X-3.3.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name |
Vendor |
Start Version |
End Version |
| Node_export |
Node_export_project |
7.x-3.0 (including) |
7.x-3.3 (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.
