CVE-2023-35980Network attack vector

Unauthenticated privileged code execution via crafted PAPI packets

Published Jul 25, 2023 · Updated Nov 7, 2024

Buffer overflow in PAPI services in HPE Aruba Access Points allows remote attackers to execute privileged code via UDP port 8211. HPE has not disclosed the affected services or the specific unchecked copy operation; crafted PAPI packets trigger memory corruption. No authentication or user interaction is required, and successful exploitation grants privileged operating-system code execution.
