Description

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.

Affected configurations

• fasterxml jackson-databind (>= 2.0.0 < 2.6.7.3) • fasterxml jackson-databind (>= 2.7.0 < 2.7.9.6) • fasterxml jackson-databind (>= 2.8.0 < 2.8.11.4) • fasterxml jackson-databind (>= 2.9.0 < 2.9.9) • debian debian linux 8.0 • debian debian linux 9.0
