There is a potential remote code execution (RCE) vulnerability, if user is

  1. handling untrusted content (where attacker can craft JSON)
  2. using "Default Typing" feature (or equivalent; polymorphic value with base type of java.lang.Object
  3. has oracle JDBC driver jar in classpath
  4. allows connections from service to untrusted hosts (where attacker can run an LDAP service)

(note: steps 1 and 2 are common steps as explained in https://medium.com/@cowtowncoder/on-jackson-cves-dont-panic-here-is-what-you-need-to-know-54cd0d6e8062)

To solve the issue, 2 types from JDBC driver are blacklisted to avoid their use as "serialization gadgets".
