CVE-2023-40619

phpPgAdmin 7.14.4 and earlier is vulnerable to deserialization of untrusted data which may lead to remote code execution because user-controlled data is directly passed to the PHP unserialize() function in multiple places. An example is the functionality to manage tables in tables.php where the ma[] POST parameter is deserialized.

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.
