An issue was discovered in Hyland OnBase 16.0.2.83 and below, 17.0.2.109 and below, 18.0.0.37 and below, 19.8.16.1000 and below and 20.3.10.1000 and below. It uses XML deserialization libraries in an unsafe manner.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Onbase Hyland * 16.0.2.83 (including)
Onbase Hyland 17.0.0.0 (including) 17.0.2.109 (including)
Onbase Hyland 18.0.0.0 (including) 18.0.0.37 (including)
Onbase Hyland 19.0.0.0 (including) 19.8.16.1000 (including)
Onbase Hyland 20.0.0.0 (including) 20.3.10.1000 (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.
