CVE-2021-1392 – Cisco IOS and IOS XE Software Common Industrial Protocol Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1392
A vulnerability in the CLI command permissions of Cisco IOS and Cisco IOS XE Software could allow an authenticated, local attacker to retrieve the password for Common Industrial Protocol (CIP) and then remotely configure the device as an administrative user. This vulnerability exists because incorrect permissions are associated with the show cip security CLI command. An attacker could exploit this vulnerability by issuing the command to retrieve the password for CIP on an affected device. A successful exploit could allow the attacker to reconfigure the device. Una vulnerabilidad en los permisos de comando de la CLI del Software Cisco IOS y Cisco IOS XE, podría permitir a un atacante local autenticado recuperar la contraseña para el Protocolo industrial común (CIP) y luego configurar remotamente el dispositivo como un usuario administrativo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-SAP-OPLbze68 • CWE-522: Insufficiently Protected Credentials •
CVE-2021-1460 – Cisco IOx Application Framework Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1460
A vulnerability in the Cisco IOx Application Framework of Cisco 809 Industrial Integrated Services Routers (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, and Cisco IC3000 Industrial Compute Gateway could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error handling during packet processing. An attacker could exploit this vulnerability by sending a high and sustained rate of crafted TCP traffic to the IOx web server on an affected device. A successful exploit could allow the attacker to cause the IOx web server to stop processing requests, resulting in a DoS condition. Una vulnerabilidad en el Cisco IOx Application Framework de los Enrutadores Cisco 809 Industrial Integrated Services (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, y Cisco IC3000 Industrial Compute Gateway, podría permitir a un atacante remoto no autenticado causar una denegación de servicio. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-dos-4Fgcjh6 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-3408 – Cisco IOS and IOS XE Software Split DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3408
A vulnerability in the Split DNS feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability occurs because the regular expression (regex) engine that is used with the Split DNS feature of affected releases may time out when it processes the DNS name list configuration. An attacker could exploit this vulnerability by trying to resolve an address or hostname that the affected device handles. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad Split DNS de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-splitdns-SPWqpdGW • CWE-185: Incorrect Regular Expression CWE-400: Uncontrolled Resource Consumption •
CVE-2020-3409 – Cisco IOS and IOS XE Software PROFINET Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3409
A vulnerability in the PROFINET feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to crash and reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted PROFINET packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted PROFINET packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to crash and reload, resulting in a DoS condition on the device. Una vulnerabilidad en la funcionalidad PROFINET de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se bloquee y recargue, resultando en una condición de denegación de servicio (DoS) en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-profinet-J9QMCHPB • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVE-2020-3476 – Cisco IOS XE Software Arbitrary File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2020-3476
A vulnerability in the CLI implementation of a specific command of Cisco IOS XE Software could allow an authenticated, local attacker to overwrite arbitrary files in the underlying host file system. The vulnerability is due to insufficient validation of the parameters of a specific CLI command. An attacker could exploit this vulnerability by issuing that command with specific parameters. A successful exploit could allow the attacker to overwrite the content of any arbitrary file that resides on the underlying host file system. Una vulnerabilidad en la implementación de un comando específico de la CLI de Cisco IOS XE Software, podría permitir a un atacante local autenticado sobrescribir archivos arbitrarios en el sistema de archivos del host subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-file-overwrite-Ynu5PrJD • CWE-552: Files or Directories Accessible to External Parties •
