CVE-2026-73765Network attack vector

Remote code execution via authenticated API path traversal

Published Sep 1, 2026 · Updated Sep 3, 2026

Path traversal in HPE AOS-CX API endpoints allows remote authenticated users to write arbitrary files to the underlying operating system. HPE identifies the locus only as API endpoints and has not disclosed which handlers accept traversal paths or how pathname validation fails. Administrative API privileges are required, and a strategically placed file enables remote code execution on the switch.
