Description

This security bulletin contains information about 1 vulnerability.


1) Missing initialization of resource (CVE-ID: CVE-2021-28167)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.
