CVE-2017-11153

Deserialization vulnerability in synophoto_csPhotoMisc.php in Synology Photo Station before 6.7.3-3432 and 6.3-2967 allows remote attackers to gain administrator privileges via a crafted serialized payload.

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.
