1) Missing initialization of resource

EUVDB-ID: #VU60084

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-28167

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

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.

Mitigation

Install update from vendor's website.
