Vulnerability Details

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Oracle JDBC jar in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

Research direction

Start with samples/client/petstore/scala/build.gradle and samples/client/petstore/java/jersey1/build.gradle, then inspect how swagger-core brings in jackson-databind. Update the dependency versions using the stated fix resolution and run the relevant Gradle builds to confirm both vulnerable versions are gone.
