Description
The disclosed vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.
The vulnerability exists due to fail to block the jboss-common-coreclass from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input to perform unauthorized actions on the system, which could allow the attacker to execute arbitrary code or cause a denial of service (DoS) condition.
