CVE-2019-17076

An issue was discovered in Jamf Pro 9.x and 10.x before 10.15.1. Deserialization of untrusted data when parsing JSON in several APIs may cause Denial of Service (DoS), remote code execution (RCE), and/or deletion of files on the Jamf Pro server.

Weakness

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

Affected Software

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.
