CVE-2022-20676 – Cisco IOS XE Software Tool Command Language Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-20676
A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS XE Software could allow an authenticated, local attacker to escalate from privilege level 15 to root-level privileges. This vulnerability is due to insufficient input validation of data that is passed into the Tcl interpreter. An attacker could exploit this vulnerability by loading malicious Tcl code on an affected device. A successful exploit could allow the attacker to execute arbitrary commands as root. By default, Tcl shell access requires privilege level 15. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-priv-esc-grbtubU • CWE-20: Improper Input Validation CWE-250: Execution with Unnecessary Privileges •
CVE-2022-20677 – Cisco IOx Application Hosting Environment Vulnerabilities
https://notcve.org/view.php?id=CVE-2022-20677
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el entorno de alojamiento de aplicaciones Cisco IOx en varias plataformas de Cisco podrían permitir a un atacante inyectar comandos arbitrarios en el sistema operativo del host subyacente, ejecutar código arbitrario en el sistema operativo del host subyacente, instalar aplicaciones sin estar autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.

CVE-2022-20678 – Cisco IOS XE Software AppNav-XE Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20678
A vulnerability in the AppNav-XE feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of certain TCP segments. An attacker could exploit this vulnerability by sending a stream of crafted TCP traffic at a high rate through an interface of an affected device. That interface would need to have AppNav interception enabled. A successful exploit could allow the attacker to cause the device to reload. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appnav-xe-dos-j5MXTR4 • CWE-413: Improper Resource Locking CWE-755: Improper Handling of Exceptional Conditions •
CVE-2022-20679 – Cisco IOS XE Software IPSec Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20679
A vulnerability in the IPSec decryption routine of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to buffer exhaustion that occurs while traffic on a configured IPsec tunnel is being processed. An attacker could exploit this vulnerability by sending traffic to an affected device that has a maximum transmission unit (MTU) of 1800 bytes or greater. A successful exploit could allow the attacker to cause the device to reload. To exploit this vulnerability, the attacker may need access to the trusted network where the affected device is in order to send specific packets to be processed by the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-qfp-ipsec-GQmqvtqV • CWE-20: Improper Input Validation •
CVE-2022-20681 – Cisco IOS XE Software for Cisco Catalyst 9000 Family Switches and Catalyst 9000 Family Wireless Controllers Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-20681
A vulnerability in the CLI of Cisco IOS XE Software for Cisco Catalyst 9000 Family Switches and Cisco Catalyst 9000 Family Wireless Controllers could allow an authenticated, local attacker to elevate privileges to level 15 on an affected device. This vulnerability is due to insufficient validation of user privileges after the user executes certain CLI commands. An attacker could exploit this vulnerability by logging in to an affected device as a low-privileged user and then executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands with level 15 privileges on the affected device. Una vulnerabilidad en la CLI del software Cisco IOS XE para Cisco Catalyst 9000 Family Switches and Cisco Catalyst 9000 Family Wireless Controllers podría permitir a un atacante local autenticado elevar los privilegios al nivel 15 en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-priv-esc-ybvHKO5 • CWE-266: Incorrect Privilege Assignment •
