CVSS: 7.2EPSS: 0%CPEs: 49EXPL: 0CVE-2021-34725 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-34725
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root-level privileges on the underlying operating system. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to execute commands with root-level privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-maapi-privesc-KSUg7QSS • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.6EPSS: 0%CPEs: 49EXPL: 0CVE-2021-34724 – Cisco IOS XE SD-WAN Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34724
A vulnerability in the Cisco IOS XE SD-WAN Software CLI could allow an authenticated, local attacker to elevate privileges and execute arbitrary code on the underlying operating system as the root user. An attacker must be authenticated on an affected device as a PRIV15 user. This vulnerability is due to insufficient file system protection and the presence of a sensitive file in the bootflash directory on an affected device. An attacker could exploit this vulnerability by overwriting an installer file stored in the bootflash directory with arbitrary commands that can be executed with root-level privileges. A successful exploit could allow the attacker to read and write changes to the configuration database on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxesdwan-privesc-VP4FG3jD • CWE-284: Improper Access Control •
CVSS: 6.9EPSS: 0%CPEs: 24EXPL: 0CVE-2021-34723 – Cisco IOS XE SD-WAN Software Arbitrary File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2021-34723
A vulnerability in a specific CLI command that is run on Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the configuration database of an affected device. This vulnerability is due to insufficient validation of specific CLI command parameters. 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 the configuration database and gain root-level access to an affected device. Una vulnerabilidad en un comando CLI específico que se ejecuta en Cisco IOS XE SD-WAN Software podría permitir a un atacante local autenticado sobrescribir archivos arbitrarios en la base de datos de configuración de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxesdwan-arbfileov-MVOF3ZZn • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 8.6EPSS: 0%CPEs: 20EXPL: 0CVE-2021-1624 – Cisco IOS XE Software Rate Limiting Network Address Translation Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1624
A vulnerability in the Rate Limiting Network Address Translation (NAT) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause high CPU utilization in the Cisco QuantumFlow Processor of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to mishandling of the rate limiting feature within the QuantumFlow Processor. An attacker could exploit this vulnerability by sending large amounts of traffic that would be subject to NAT and rate limiting through an affected device. A successful exploit could allow the attacker to cause the QuantumFlow Processor utilization to reach 100 percent on the affected device, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad Rate Limiting Network Address Translation (NAT) de Cisco IOS XE Software podría permitir a un atacante remoto no autenticado causar un alto uso de la CPU en el procesador Cisco QuantumFlow de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ratenat-pYVLA7wM • CWE-399: Resource Management Errors •
