Description
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to usage of the jdk.internal.reflect.ConstantPool API causes the JVM in some cases to pre-resolve certain constant pool entries. This allows a user to call static methods or access static members without running the class initialization method. A remote attacker can send a specially crafted request to the application and observe uninitialized values.
Remediation
Install updates from vendor's website.
