A vulnerability was found in WuKongOpenSource Wukong_nocode up to 20230807. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file ExpressionUtil.java of the component AviatorScript Handler. The manipulation leads to deserialization. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The associated identifier of this vulnerability is VDB-271051.

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.
