The vulnerability is due to improper boundary restrictions on user-supplied input in the Guest user feature of the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device triggering a buffer overflow condition. A successful exploit could allow the attacker to cause the device to stop responding resulting in a denial of service condition or could allow the attacker to execute arbitrary code.
