Sunnet eHRD e-mail delivery task schedule’s serialization function has inadequate input object validation and restriction, which allows a post-authenticated remote attacker with database access privilege, to execute arbitrary code and control the system or interrupt services.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Ehrd Sun 8 (including) 8 (including)
Ehrd Sun 9 (including) 9 (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.
