Technical details

Multiple stack-based buffer overflow vulnerabilities (CWE-121) exist within the management service components of Aruba AOS-8 and AOS-10. The flaw is accessible via the Command-Line Interface (CLI) and is triggered when the system processes specially crafted requests. An attacker must be authenticated with high-level administrative privileges to exploit this vulnerability. Successful exploitation allows for arbitrary code execution with elevated privileges on the underlying operating system. The vulnerability is reachable over the network (AV:N) but requires prior administrative access (PR:H).
