CVE-2020-3217 – Cisco IOS, IOS XE, IOS XR, and NX-OS Software One Platform Kit Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3217
A vulnerability in the Topology Discovery Service of Cisco One Platform Kit (onePK) in Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient length restrictions when the onePK Topology Discovery Service parses Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol message to an affected device. An exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges, or to cause a process crash, which could result in a reload of the device and cause a DoS condition. Una vulnerabilidad en el Topology Discovery Service de Cisco One Platform Kit (onePK) en Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, y Cisco NX-OS Software, podría permitir a un atacante adyacente no autenticado ejecutar código arbitrario o causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-nxos-onepk-rce-6Hhyt4dC • CWE-20: Improper Input Validation •
CVE-2020-3215 – Cisco IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3215
A vulnerability in the Virtual Services Container of Cisco IOS XE Software could allow an authenticated, local attacker to gain root-level privileges on an affected device. The vulnerability is due to insufficient validation of a user-supplied open virtual appliance (OVA). An attacker could exploit this vulnerability by installing a malicious OVA on an affected device. Una vulnerabilidad en el Virtual Services Container de Cisco IOS XE Software, podría permitir a un atacante local autenticado conseguir privilegios de nivel root sobre un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de un open virtual appliance (OVA) suministrado por el usuario. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-priv-esc1-OKMKFRhV • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVE-2020-3213 – Cisco IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3213
A vulnerability in the ROMMON of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to those of the root user of the underlying operating system. The vulnerability is due to the ROMMON allowing for special parameters to be passed to the device at initial boot up. An attacker could exploit this vulnerability by sending parameters to the device at initial boot up. An exploit could allow the attacker to elevate from a Priv15 user to the root user and execute arbitrary commands with the privileges of the root user. Una vulnerabilidad en el ROMMON de Cisco IOS XE Software, podría permitir a un atacante local autenticado elevar los privilegios a los del usuario root del sistema operativo subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-priv-esc3-GMgnGCHx • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2020-3209 – Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3209
A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device. Una vulnerabilidad en la verificación de la imagen del software en Cisco IOS XE Software, podría permitir a un atacante físico no autenticado instalar y arrancar una imagen de software malicioso o ejecutar archivos binarios sin firmar sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-digsig-bypass-FYQ3bmVq • CWE-347: Improper Verification of Cryptographic Signature •
CVE-2020-3207 – Cisco IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3207
A vulnerability in the processing of boot options of specific Cisco IOS XE Software switches could allow an authenticated, local attacker with root shell access to the underlying operating system (OS) to conduct a command injection attack during device boot. This vulnerability is due to insufficient input validation checks while processing boot options. An attacker could exploit this vulnerability by modifying device boot options to execute attacker-provided code. A successful exploit may allow an attacker to bypass the Secure Boot process and execute malicious code on an affected device with root-level privileges. Una vulnerabilidad en el procesamiento de las opciones de arranque de los switches específicos de Cisco IOS XE Software, podría permitir a un atacante local autenticado con acceso de shell root al sistema operativo (SO) subyacente llevar a cabo un ataque de inyección de comando durante el arranque del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ngwc-cmdinj-KEwWVWR • 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') •
