CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1485 – Cisco IOS XR Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1485
A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges on the underlying Linux operating system (OS) of an affected device. This vulnerability is due to insufficient input validation of commands that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to an affected command. A successful exploit could allow the attacker to execute commands on the underlying Linux OS with root privileges. Una vulnerabilidad en la CLI del software Cisco IOS XR, podría permitir a un atacante local autenticado inyectar comandos arbitrarios que son ejecutados con privilegios root en el sistema operativo (SO) subyacente de Linux de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xr-cmdinj-vsKGherc • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

https://notcve.org/view.php?id=CVE-2021-1313
Multiple vulnerabilities in the ingress packet processing function of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en la función de procesamiento de paquetes de entrada de Cisco IOS XR Software, podrían permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. Para mayor información sobre estas vulnerabilidades, consulte la sección Detalles de este aviso • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-dos-WwDdghs2 • CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2021-1370 – Cisco IOS XR Software for Cisco 8000 Series Routers and Network Convergence System 540 Series Routers Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1370
A vulnerability in a CLI command of Cisco IOS XR Software for the Cisco 8000 Series Routers and Network Convergence System 540 Series Routers running NCS540L software images could allow an authenticated, local attacker to elevate their privilege to root. To exploit this vulnerability, an attacker would need to have a valid account on an affected device. The vulnerability is due to insufficient validation of command line arguments. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the prompt. A successful exploit could allow an attacker with low-level privileges to escalate their privilege level to root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-pe-QpzCAePe • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.5EPSS: 0%CPEs: 14EXPL: 0CVE-2021-1389 – Cisco IOS XR and Cisco NX-OS Software IPv6 Access Control List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1389
A vulnerability in the IPv6 traffic processing of Cisco IOS XR Software and Cisco NX-OS Software for certain Cisco devices could allow an unauthenticated, remote attacker to bypass an IPv6 access control list (ACL) that is configured for an interface of an affected device. The vulnerability is due to improper processing of IPv6 traffic that is sent through an affected device. An attacker could exploit this vulnerability by sending crafted IPv6 packets that traverse the affected device. A successful exploit could allow the attacker to access resources that would typically be protected by the interface ACL. Una vulnerabilidad en el procesamiento del tráfico IPv6 del Software Cisco IOS XR, y el Software Cisco NX-OS para determinados dispositivos Cisco, podría permitir a un atacante remoto no autenticado omitir una lista de control de acceso (ACL) IPv6 configurada para una interfaz de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipv6-acl-CHgdYk8j • CWE-284: Improper Access Control •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-1128 – Cisco IOS XR Software Unauthorized Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1128
A vulnerability in the CLI parser of Cisco IOS XR Software could allow an authenticated, local attacker to view more information than their privileges allow. The vulnerability is due to insufficient application of restrictions during the execution of a specific command. An attacker could exploit this vulnerability by using a specific command at the command line. A successful exploit could allow the attacker to obtain sensitive information within the configuration that otherwise might not have been accessible beyond the privileges of the invoking user. Una vulnerabilidad en el analizador de la CLI del Software Cisco IOS XR, podría permitir a un atacante autenticado local visualizar más información de la que sus privilegios permiten. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-infodisc-4mtm9Gyt • CWE-201: Insertion of Sensitive Information Into Sent Data •
