CVE-2024-23052

An issue in WuKongOpenSource WukongCRM v.72crm_9.0.1_20191202 allows a remote attacker to execute arbitrary code via the parseObject() function in the fastjson component.

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.
