CVSS: 7.1EPSS: 0%CPEs: 234EXPL: 0CVE-2022-20694 – Cisco IOS XE Software Border Gateway Protocol Resource Public Key Infrastructure Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20694
A vulnerability in the implementation of the Resource Public Key Infrastructure (RPKI) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the Border Gateway Protocol (BGP) process to crash, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of a specific RPKI to Router (RTR) Protocol packet header. An attacker could exploit this vulnerability by compromising the RPKI validator server and sending a specifically crafted RTR packet to an affected device. Alternatively, the attacker could use man-in-the-middle techniques to impersonate the RPKI validator server and send a crafted RTR response packet over the established RTR TCP connection to the affected device. A successful exploit could allow the attacker to cause a DoS condition because the BGP process could constantly restart and BGP routing could become unstable. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-rpki-dos-2EgCNeKE • CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2022-20718
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el entorno de alojamiento de aplicaciones Cisco IOx en varias plataformas de Cisco podrían permitir a un atacante inyectar comandos arbitrarios en el sistema operativo anfitrión subyacente, ejecutar código arbitrario en el sistema operativo anfitrión subyacente, instalar aplicaciones sin ser autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.

CVSS: 7.8EPSS: 0%CPEs: 115EXPL: 0CVE-2021-1529 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1529
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges. The vulnerability is due to insufficient input validation by the system CLI. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges.

https://notcve.org/view.php?id=CVE-2021-1616
A vulnerability in the H.323 application level gateway (ALG) used by the Network Address Translation (NAT) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass the ALG. This vulnerability is due to insufficient data validation of traffic that is traversing the ALG. An attacker could exploit this vulnerability by sending crafted traffic to a targeted device. A successful exploit could allow the attacker to bypass the ALG and open connections that should not be allowed to a remote device located behind the ALG. Note: This vulnerability has been publicly discussed as NAT Slipstreaming. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-h323alg-bypass-4vy2MP2Q • CWE-693: Protection Mechanism Failure •
