A deserialization of untrusted data vulnerability in the download file function of Soar Cloud HRD Human Resource Management System through version 7.3.2025.0408 allows remote attackers to execute arbitrary system commands via a crafted serialized object.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Hr_portal | Scshr | * | 7.3.2025.0408 (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.
