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.
