CVE-2020-3201 – Cisco IOS and IOS XE Software Tcl Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3201
A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, local attacker with privileged EXEC credentials to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient input validation of data passed to the Tcl interpreter. An attacker could exploit this vulnerability by executing crafted Tcl arguments on an affected device. An exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en el intérprete Tool Command Language (Tcl) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante local autenticado con credenciales EXEC privilegiadas causar una condición de denegación de servicio (DoS) en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-tcl-dos-MAZQUnMF • CWE-20: Improper Input Validation •
CVE-2019-16011 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-16011
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the CLI utility. The attacker must be authenticated to access the CLI utility. A successful exploit could allow the attacker to execute commands with root privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xesdwcinj-AcQ5MxCn • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVE-2019-1950 – Cisco IOS XE SD-WAN Software Default Credentials Vulnerability
https://notcve.org/view.php?id=CVE-2019-1950
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-cred-EVGSF259 • CWE-255: Credentials Management Errors CWE-1188: Initialization of a Resource with an Insecure Default •
CVE-2019-12666 – Cisco IOS XE Software Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2019-12666
A vulnerability in the Guest Shell of Cisco IOS XE Software could allow an authenticated, local attacker to perform directory traversal on the base Linux operating system of Cisco IOS XE Software. The vulnerability is due to incomplete validation of certain commands. An attacker could exploit this vulnerability by first accessing the Guest Shell and then entering specific commands. A successful exploit could allow the attacker to execute arbitrary code on the base Linux operating system. Una vulnerabilidad en el Guest Shell del Software Cisco IOS XE, podría permitir a un atacante local autenticado realizar un salto de directorio en el sistema operativo base Linux del software Cisco IOS XE. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-dt • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2019-12671 – Cisco IOS XE Software Consent Token Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-12671
A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS). The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the CLI and requesting shell access on an affected device. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS. Una vulnerabilidad en la CLI del Software Cisco IOS XE, podría permitir a un atacante local autenticado conseguir acceso de shell en un dispositivo afectado y ejecutar comandos sobre el sistema operativo (SO) subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-ctbypass • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
