CVE-2024-47074

DataEase is an open source data visualization analysis tool. In Dataease, the PostgreSQL data source in the data source function can customize the JDBC connection parameters and the PG server target to be connected. In backend/src/main/java/io/dataease/provider/datasource/JdbcProvider.java, PgConfiguration class dont filter any parameters, directly concat user input. So, if the attacker adds some parameters in JDBC url, and connect to evil PG server, the attacker can trigger the PG jdbc deserialization vulnerability, and eventually the attacker can execute through the deserialization vulnerability system commands and obtain server privileges. The vulnerability has been fixed in v1.18.25.

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.
