CVSS: 8.5EPSS: 0%CPEs: 61EXPL: 0CVE-2021-1443 – Cisco IOS XE Software Web UI OS Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1443
A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying operating system of an affected device. The vulnerability exists because the affected software improperly sanitizes values that are parsed from a specific configuration file. An attacker could exploit this vulnerability by tampering with a specific configuration file and then sending an API call. A successful exploit could allow the attacker to inject arbitrary code that would be executed on the underlying operating system of the affected device. To exploit this vulnerability, the attacker would need to have a privileged set of credentials to the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-os-cmd-inj-Ef6TV5e9 • 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: 7.8EPSS: 0%CPEs: 224EXPL: 0CVE-2021-1442 – Cisco IOS XE Software Plug-and-Play Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1442
A vulnerability in a diagnostic command for the Plug-and-Play (PnP) subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to the level of an Administrator user (level 15) on an affected device. The vulnerability is due to insufficient protection of sensitive information. An attacker with low privileges could exploit this vulnerability by issuing the diagnostic CLI show pnp profile when a specific PnP listener is enabled on the device. A successful exploit could allow the attacker to obtain a privileged authentication token. This token can be used to send crafted PnP messages and execute privileged commands on the targeted system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-pnp-priv-esc-AmG3kuVL • CWE-532: Insertion of Sensitive Information into Log File •

https://notcve.org/view.php?id=CVE-2021-1436
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to conduct path traversal attacks and obtain read access to sensitive files on an affected system. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to view arbitrary files on the affected system. Una vulnerabilidad en la CLI del Software Cisco IOS XE SD-WAN, podría permitir a un atacante local autenticado llevar a cabo ataques de salto de ruta y obtener acceso de lectura a archivos confidenciales en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-sdwpathtrav-nsrue2Mt • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2021-1435
A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to inject arbitrary commands that can be executed as the root user. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted request to the web UI of an affected device with arbitrary commands injected into a portion of the request. A successful exploit could allow the attacker to execute arbitrary commands as the root user. Una vulnerabilidad en la Interfaz de Usuario Web del Software Cisco IOS XE, podría permitir a un atacante remoto autenticado inyectar comandos arbitrarios que se pueden ejecutar como usuario root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-webcmdinjsh-UFJxTgZD • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2021-1434
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the underlying file system. This 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 CLI del Software Cisco IOS XE SD-WAN, podría permitir a un atacante local autenticado sobrescribir archivos arbitrarios en el sistema de archivos subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-arbfile-FUxskKDE • CWE-552: Files or Directories Accessible to External Parties •
