https://notcve.org/view.php?id=CVE-2021-34708
Multiple vulnerabilities in image verification checks of Cisco Network Convergence System (NCS) 540 Series Routers, only when running Cisco IOS XR NCS540L software images, and Cisco IOS XR Software for Cisco 8000 Series Routers could allow an authenticated, local attacker to execute arbitrary code on the underlying operating system. For more information about these vulnerabilities, see the Details section of this advisory. Varias vulnerabilidades en las comprobaciones de verificación de imágenes de los routers Cisco Network Convergence System (NCS) de la serie 540, sólo cuando se ejecutan imágenes de software Cisco IOS XR NCS540L, y el software Cisco IOS XR para los routers Cisco de la serie 8000 podrían permitir a un atacante local autenticado ejecutar código arbitrario en el sistema operativo subyacente.

CVSS: 6.8EPSS: 0%CPEs: 15EXPL: 0CVE-2021-33478
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: 9.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-1716 – Cisco IP Phone 7800 Series and 8800 Series Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2019-1716
A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code. The vulnerability exists because the software improperly validates user-supplied input during user authentication. An attacker could exploit this vulnerability by connecting to an affected device using HTTP and supplying malicious user credentials. A successful exploit could allow the attacker to trigger a reload of an affected device, resulting in a DoS condition, or to execute arbitrary code with the privileges of the app user. Cisco fixed this vulnerability in the following SIP Software releases: 10.3(1)SR5 and later for Cisco Unified IP Conference Phone 8831; 11.0(4)SR3 and later for Cisco Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 and later for the rest of the Cisco IP Phone 7800 Series and 8800 Series. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190320-ip-phone-rce • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2019-1763 – Cisco IP Phone 8800 Series Authorization Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1763
A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to bypass authorization, access critical services, and cause a denial of service (DoS) condition. The vulnerability exists because the software fails to sanitize URLs before it handles requests. An attacker could exploit this vulnerability by submitting a crafted URL. A successful exploit could allow the attacker to gain unauthorized access to critical services and cause a DoS condition. This vulnerability affects Cisco IP Phone 8800 Series products running a SIP Software release prior to 11.0(5) for Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 for the IP Conference Phone 8832 and the rest of the IP Phone 8800 Series. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190320-ipab • CWE-284: Improper Access Control •
CVSS: 8.8EPSS: 0%CPEs: 8EXPL: 0CVE-2019-1764 – Cisco IP Phone 8800 Series Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-1764
A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user. This vulnerability affects Cisco IP Phone 8800 Series products running a SIP Software release prior to 11.0(5) for Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 for the IP Conference Phone 8832 and the rest of the IP Phone 8800 Series. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190320-ip-phone-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
