HighMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions
Eclipse OpenJ9 version 0.8
Description
The issue is related to the Java Attach API, which is enabled by default on Windows, Linux, and AIX JVMs. This allows users other than the process owner to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and execute untrusted native code using Attach API operations. The vulnerability may also be related to the recovery of an invalid data structure in memory, potentially allowing an attacker to execute arbitrary code. A local attacker could exploit this to gain elevated privileges on the system.
Recommendations
For Eclipse OpenJ9 version 0.8, consider disabling the Java Attach API using the command line option -Dcom.ibm.tools.attach.enable=no as a temporary workaround to minimize the risk of exploitation.
