Descriptions

A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.

Se descubrió un problema de tipificación polimórfica en FasterXML jackson-databind 2.x antes del 2.9.9. Cuando la escritura predeterminada está habilitada (ya sea globalmente o para una propiedad específica) para un dispositivo remoto JSON expuesto externamente, el servicio tiene el myjq-connector-java jar (8.0.14 o anterior) en el classpath, y un atacante puede alojar un servidor MySQL creado accesible por la víctima, pudiendo enviar un mensaje JSON diseñado que les permite leer archivos locales arbitrarios en el servidor. Esto ocurre debido a la falta de validación com.mysql.cj.jdbc.admin.MiniAdmin.
