Описание
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.
Отчет
Red Hat Satellite 6 does not enable polymorphic unmarshmalling, which is a required configuration for the vulnerability to be used. We may update the jackson-databind dependency in a future release.
Меры по смягчению последствий
The following conditions are needed for an exploit, we recommend avoiding all if possible
- Deserialization from sources you do not control
enableDefaultTyping()@JsonTypeInfo usingid.CLASSorid.MINIMAL_CLASS`
