CVSS: 4.6EPSS: 0%CPEs: 40EXPL: 1CVE-2022-20660 – Cisco IP Phones Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-20660
A vulnerability in the information storage architecture of several Cisco IP Phone models could allow an unauthenticated, physical attacker to obtain confidential information from an affected device. This vulnerability is due to unencrypted storage of confidential information on an affected device. An attacker could exploit this vulnerability by physically extracting and accessing one of the flash memory chips. A successful exploit could allow the attacker to obtain confidential information from the device, which could be used for subsequent attacks. Una vulnerabilidad en la arquitectura de almacenamiento de información de varios modelos de teléfonos IP de Cisco podría permitir a un atacante físico no autenticado obtener información confidencial de un dispositivo afectado. • http://packetstormsecurity.com/files/165567/Cisco-IP-Phone-Cleartext-Password-Storage.html http://seclists.org/fulldisclosure/2022/Jan/34 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ip-phone-info-disc-fRdJfOxA • CWE-312: Cleartext Storage of Sensitive Information •
CVSS: 5.5EPSS: 0%CPEs: 32EXPL: 0CVE-2021-34711 – Cisco IP Phone Software Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2021-34711
A vulnerability in the debug shell of Cisco IP Phone software could allow an authenticated, local attacker to read any file on the device file system. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by providing crafted input to a debug shell command. A successful exploit could allow the attacker to read any file on the device file system. Una vulnerabilidad en el shell de depuración del software de Cisco IP Phone podría permitir a un atacante local autenticado leer cualquier archivo del sistema de archivos del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipphone-arbfileread-NPdtE2Ow • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-36: Absolute Path Traversal •

https://notcve.org/view.php?id=CVE-2021-33478
The TrustZone implementation in certain Broadcom MediaxChange firmware could allow an unauthenticated, physically proximate attacker to achieve arbitrary code execution in the TrustZone Trusted Execution Environment (TEE) of an affected device. This, for example, affects certain Cisco IP Phone and Wireless IP Phone products before 2021-07-07. Exploitation is possible only when the attacker can disassemble the device in order to control the voltage/current for chip pins. La implementación de TrustZone en determinados firmware de Broadcom MediaxChange, podría permitir a un atacante no autenticado y físicamente próximo lograr la ejecución de código arbitrario en el TrustZone Trusted Execution Environment (TEE) de un dispositivo afectado. Esto, por ejemplo, afecta a determinados productos Cisco IP Phone y Wireless IP Phone anteriores a 2021-07-07. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-brcm-mxc-jul2021-26LqUZUh • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2020-3574 – Cisco IP Phone TCP Packet Flood Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3574
A vulnerability in the TCP packet processing functionality of Cisco IP Phones could allow an unauthenticated, remote attacker to cause the phone to stop responding to incoming calls, drop connected calls, or unexpectedly reload. The vulnerability is due to insufficient TCP ingress packet rate limiting. An attacker could exploit this vulnerability by sending a high and sustained rate of crafted TCP traffic to the targeted device. A successful exploit could allow the attacker to impact operations of the phone or cause the phone to reload, leading to a denial of service (DoS) condition. Una vulnerabilidad en la funcionalidad TCP packet processing de Cisco IP Phones, podría permitir a un atacante remoto no autenticado causar que el teléfono dejara de responder a las llamadas entrantes, abandonara las llamadas conectadas o se recargara inesperadamente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-voip-phone-flood-dos-YnU9EXOv • CWE-371: State Issues •
CVSS: 8.8EPSS: 0%CPEs: 54EXPL: 0CVE-2020-3111 – Cisco IP Phone Remote Code Execution and Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3111
A vulnerability in the Cisco Discovery Protocol implementation for the Cisco IP Phone could allow an unauthenticated, adjacent attacker to remotely execute code with root privileges or cause a reload of an affected IP phone. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. 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 denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. • http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-voip-phones-rce-dos • CWE-20: Improper Input Validation •
