CVSS v3.1

Official Description

In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int, byte[], int) method does not verify that the provided byte array is non-null nor that the provided index is in bounds when compiled by the JIT. This allows arbitrary writes to any 32-bit address or beyond the end of a byte array within Java code run under a SecurityManager.

Technical Analysis

CVE-2019-11772 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
