CVE-2021-37728Network attack vector

Critical-file modification via authenticated CLI path traversal

Published Sep 7, 2021 · Updated Aug 4, 2024

Path traversal in HPE ArubaOS before 8.8.0.1, 8.7.1.4, 8.6.0.11, or 8.5.0.13 allows remote authenticated users to alter critical files. The CLI accepts path input that escapes its intended directory boundary, but HPE has not identified the affected command or parameter. High-privileged CLI access is required; exploitation can modify sensitive data and interrupt the ArubaOS instance.
