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 •
CVSS: 10.0EPSS: 3%CPEs: 44EXPL: 3CVE-2020-3161 – Cisco IP Phones Web Server Remote Code Execution and Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3161
A vulnerability in the web server for Cisco IP Phones could allow an unauthenticated, remote attacker to execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. The vulnerability is due to a lack of proper input validation of HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web server of a targeted device. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a DoS condition. Una vulnerabilidad en el servidor web de Cisco IP Phones, podría permitir a un atacante no autenticado remoto ejecutar código con privilegios root o causar una recarga de un teléfono IP afectado, resultando en una condición de denegación de servicio (DoS). • https://www.exploit-db.com/exploits/48342 https://github.com/abood05972/CVE-2020-3161 http://packetstormsecurity.com/files/157265/Cisco-IP-Phone-11.7-Denial-Of-Service.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-voip-phones-rce-dos-rB6EeRXs • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 80EXPL: 0CVE-2019-1635 – Cisco IP Phone 7800 Series and 8800 Series Session Initiation Protocol XML Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1635
A vulnerability in the call-handling functionality of Session Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to incomplete error handling when XML data within a SIP packet is parsed. An attacker could exploit this vulnerability by sending a SIP packet that contains a malicious XML payload to an affected phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition. Una vulnerabilidad en la funcionalidad de manejo de llamadas (call-handling) del Software Session Initiation Protocol (SIP) para teléfonos IP 7800 Series y 8800 Series de Cisco, podría permitir que un atacante remoto no identificado haga que un teléfono afectado se recargue inesperadamente, resultando en una condición de Denegación de Servicio (DoS ) temporal. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-phone-sip-xml-dos • CWE-399: Resource Management Errors CWE-755: Improper Handling of Exceptional Conditions •
