Description
Buffer overflow vulnerabilities exist in an underlying service of AOS-8 that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's access point management protocol) UDP port 8211. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
