CVE-2022-31216

SYSTEM code execution via installer symbolic link

Published Jun 15, 2022 · Updated Sep 16, 2024

Link following in ABB Drive Composer installers allows local users to execute arbitrary code as SYSTEM through a crafted repair operation. The elevated installer follows an attacker-created symbolic link and writes arbitrary content to a chosen nonexistent file instead of constraining the repair target. The affected installer ships with Automation Builder 1.1.0 through 2.5.0, Drive Composer Entry and Pro 2.0 through 2.7, and Mint WorkBench build 5866 and earlier; exploitation requires low-privileged local access.
