https://notcve.org/view.php?id=CVE-2021-1379
Multiple vulnerabilities in the Cisco Discovery Protocol and Link Layer Discovery Protocol (LLDP) implementations for Cisco IP Phone Series 68xx/78xx/88xx could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP phone. These vulnerabilities are due to missing checks when the IP phone processes a Cisco Discovery Protocol or LLDP packet. ... A successful exploit could allow the attacker to execute code on the affected IP phone or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition.Note: Cisco Discovery Protocol is a Layer 2 protocol. ... Una explotación exitosa podría permitir al atacante ejecutar código en el teléfono IP afectado o hacer que se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). Nota: Cisco Discovery Protocol es un protocolo de capa 2. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipphone-rce-dos-U2PsSkz3 https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-distupd-N87eB6Z3 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
