An issue in Diebold Aglis XFS for Opteva v.4.1.61.1 allows a remote attacker to execute arbitrary code via a crafted payload to the ResolveMethod() parameter.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Agilis_xfs_for_opteva | Dieboldnixdorf | 4.1.61.1 (including) | 4.1.61.1 (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.
