CVE-2024-2054

The Artica-Proxy administrative web application will deserialize arbitrary PHP objects supplied by unauthenticated users and subsequently enable code execution as the www-data user.

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.
