CVE-2024-12429Public exploit

Authenticated file disclosure via memory-card symlink traversal

Published Jan 7, 2025 · Updated Nov 3, 2025

Path traversal in ABB AC500 V3 firmware before 3.8.0 allows physically proximate attackers to read system files via a crafted memory card. The file explorer follows an ext4 symlink targeting the filesystem root from an inserted card instead of confining access to the card. Physical access and successful device authentication are required, and exposure is limited to files readable as the system user.
