CVE-2024-37361

The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid. (CWE-502)

Hitachi Vantara Pentaho Business Analytics Server versions before 10.2.0.0 and 9.3.0.9, including 8.3.x, deserialize untrusted JSON data without constraining the parser to approved classes and methods.

When developers place no restrictions on gadget chains, or series of instances and method invocations that can self-execute during the deserialization process (i.e., before the object is returned to the caller), it is sometimes possible for attackers to leverage them to perform unauthorized actions.

Weakness

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

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.
