CVSS: 7.2EPSS: 0%CPEs: 4EXPL: 1CVE-2021-1382 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1382
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 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 the 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 privileges. • https://github.com/orangecertcc/security-research/security/advisories/GHSA-7xfm-92p7-qc57 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xesdwcinj-t68PPW7m • 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: 8.5EPSS: 0%CPEs: 5EXPL: 1CVE-2021-1384 – Cisco IOx for IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1384
A vulnerability in Cisco IOx application hosting environment of Cisco IOS XE Software could allow an authenticated, remote attacker to inject commands into the underlying operating system as the root user. This vulnerability is due to incomplete validation of fields in the application packages loaded onto IOx. An attacker could exploit this vulnerability by creating a crafted application .tar file and loading it onto the device. A successful exploit could allow the attacker to perform command injection into the underlying operating system as the root user. Una vulnerabilidad en el entorno de alojamiento de aplicaciones Cisco IOx del Software Cisco IOS XE, podría permitir a un atacante remoto autenticado inyectar comandos en el sistema operativo subyacente como usuario root. • https://github.com/orangecertcc/security-research/security/advisories/GHSA-h332-fj6p-2232 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-cmdinj-RkSURGHG • 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: 214EXPL: 0CVE-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 •
CVSS: 6.9EPSS: 0%CPEs: 257EXPL: 0CVE-2021-1398 – Cisco IOS XE Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1398
A vulnerability in the boot logic of Cisco IOS XE Software could allow an authenticated, local attacker with level 15 privileges or an unauthenticated attacker with physical access to execute arbitrary code on the underlying Linux operating system of an affected device. This vulnerability is due to incorrect validations of specific function arguments that are passed to the boot script. An attacker could exploit this vulnerability by tampering with a specific file, which an affected device would process during the initial boot process. On systems that are protected by the Unified Extensible Firmware Interface (UEFI) secure boot feature, a successful exploit could allow the attacker to execute unsigned code at boot time and bypass the image verification check in the secure boot process of the affected device. Una vulnerabilidad en la lógica de arranque del Software Cisco IOS XE, podría permitir a un atacante local autenticado con privilegios de nivel 15 o un atacante no autenticado con acceso físico ejecutar código arbitrario en el sistema operativo Linux subyacente de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-ACE-75K3bRWe • CWE-489: Active Debug Code •
CVSS: 9.8EPSS: 0%CPEs: 55EXPL: 0CVE-2021-1451 – Cisco IOS XE Software Easy Virtual Switching System Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1451
A vulnerability in the Easy Virtual Switching System (VSS) feature of Cisco IOS XE Software for Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying Linux operating system of an affected device. The vulnerability is due to incorrect boundary checks of certain values in Easy VSS protocol packets that are destined for an affected device. An attacker could exploit this vulnerability by sending crafted Easy VSS protocol packets to UDP port 5500 while the affected device is in a specific state. When the crafted packet is processed, a buffer overflow condition may occur. A successful exploit could allow the attacker to trigger a denial of service (DoS) condition or execute arbitrary code with root privileges on the underlying Linux operating system of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-evss-code-exe-8cw5VSvw • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
