https://notcve.org/view.php?id=CVE-2022-20968

A vulnerability in the Cisco Discovery Protocol processing feature of Cisco IP Phone 7800 and 8800 Series firmware could allow an unauthenticated, adjacent attacker to cause a stack overflow on an affected device. This vulnerability is due to insufficient input validation of received Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by sending crafted Cisco Discovery Protocol traffic to an affected device. A successful exploit could allow the attacker to cause a stack overflow, resulting in possible remote code execution or a denial of service (DoS) condition on an affected device. Una vulnerabilidad en la función de procesamiento de Cisco Discovery Protocol del firmware de los teléfonos IP de las series 7800 y 8800 de Cisco podría permitir que un atacante adyacente no autenticado provoque un desbordamiento de pila en un dispositivo afectado. Esta vulnerabilidad se debe a una validación de entrada insuficiente de los paquetes recibidos del Protocolo de descubrimiento de Cisco. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipp-oobwrite-8cMF5r7U • CWE-787: Out-of-bounds Write •
