Vulnerability details

The vulnerability allows a local unauthenticated attacker to gain elevated privileges on the target system.

The weakness exists due to the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. A local attacker can conduct directory traversal attack and extract compressed dump files.
