CVE-2022-37888Network attack vector

Unauthenticated code execution via PAPI packet overflow

Published Oct 6, 2022 · Updated Aug 3, 2024

Buffer overflow in PAPI services on Aruba Access Points running affected InstantOS or ArubaOS releases allows remote attackers to execute code. The services mishandle specially crafted UDP packets sent to port 8211, overflowing memory during PAPI packet processing. No authentication or user interaction is required, and successful exploitation runs arbitrary code as a privileged operating-system user.
