The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to absence of xbean-reflect/JNDI gadget blocking. A remote attacker can pass specially crafted input to the application and execute arbitrary Java code on the system, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
