PixelYourSite - Your smart PIXEL (TAG) and API Manager 10.1.1.1 was found to be vulnerable. Unvalidated user input is used directly in an unserialize function in myapp/modules/facebook/facebook-server-a sync-task.php.
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.
