CVE-2022-42280

Local privilege escalation via REST path traversal

Published Jan 13, 2023 · Updated Apr 7, 2025

Path traversal in the NVIDIA DGX Systems BMC before 00.19.07 allows local users to bypass SPX REST authorization and escalate privileges. The SPX REST authorization handler fails to constrain a crafted request path to its authorized directory before resolving it. Low-privileged local access is required; exploitation bypasses authorization and permits high-impact reads and writes without reported service interruption.
