CVE-2022-47083

A PHP Object Injection vulnerability in the unserialize() function Spitfire CMS v1.0.475 allows authenticated attackers to execute arbitrary code via sending crafted requests to the web application.

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.
