Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Leadshop | Leadshop | 1.4.0 (including) | 1.4.20 (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.
