CVE-2021-29212Network attack vector

Unauthenticated code execution via backup path traversal

Published Nov 1, 2021 · Updated Aug 3, 2024

Path traversal in HPE iLO Amplifier Pack 1.80, 1.81, 1.90, and 1.95 allows remote attackers to execute arbitrary code. The backup endpoint uses a user-supplied path in file operations without validating that the path remains within an allowed directory. No authentication or user interaction is required, and successful exploitation executes code as root on the appliance.
