Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerable class/method: SubTypeValidator.java in FasterXML jackson-databind mishandles default typing when ehcache is used via the DefaultTransactionManagerLookup gadget chain, enabling RCE
  • Exploit requires polymorphic deserialization enabled via enableDefaultTyping(), @JsonTypeInfo with Id.CLASS or Id.MINIMAL_CLASS — detect these configurations in application code or deserialization call stacks
  • Gadget chains involved: ehcache and logback JNDI gadgets — monitor for JNDI lookups (e.g., ldap://, rmi://) originating from jackson-databind deserialization context
  • Mitigation/detection condition: flag any deserialization from untrusted sources combined with enableDefaultTyping() or @JsonTypeInfo id.CLASS / id.MINIMAL_CLASS usage
  • ·Vulnerability is only exploitable when jackson-databind default typing is enabled (enableDefaultTyping()) or @JsonTypeInfo is configured with Id.CLASS or Id.MINIMAL_CLASS — applications not using these configurations are not affected
  • ·OpenShift Container Platform elasticsearch plugins ship the vulnerable component but do not perform the unsafe operations required for exploitation
  • ·OpenDaylight (shipped with Red Hat OpenStack Platform) contains vulnerable jackson-databind but does not expose it in an exploitable way
