CVE-2024-33512Network attack vector

Unauthenticated privileged code execution via PAPI buffer overflow

Published May 1, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in the authentication service in HPE ArubaOS and EdgeConnect SD-WAN allows remote attackers to execute code as a privileged user. The Local User Authentication Database service writes data from crafted PAPI packets received on UDP port 8211 beyond a stack buffer. Unauthenticated network reachability to that port is sufficient, and successful exploitation grants control with the service's underlying operating-system privileges.
