CVSS: 8.6EPSS: 0%CPEs: 322EXPL: 0CVE-2022-20919 – Cisco IOS and IOS XE Software Common Industrial Protocol Request Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20919
A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento de paquetes malformados del Protocolo Industrial Común (CIP) que se envían al software Cisco IOS y al software Cisco IOS XE podría permitir a un atacante remoto no autenticado causar una recarga no esperada del dispositivo afectado, lo que provocaría una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-cip-dos-9rTbKLt9 • CWE-248: Uncaught Exception CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.6EPSS: 0%CPEs: 364EXPL: 0CVE-2022-20848 – Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points UDP Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20848
A vulnerability in the UDP processing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to the improper processing of UDP datagrams. An attacker could exploit this vulnerability by sending malicious UDP datagrams to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad de procesamiento UDP del software Cisco IOS XE para controladores inalámbricos integrados en los puntos de acceso de la serie Catalyst 9100 podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-udp-dos-XDyEwhNz • CWE-399: Resource Management Errors •
CVSS: 8.8EPSS: 0%CPEs: 131EXPL: 0CVE-2020-3141 – Cisco IOS XE Software Privilege Escalation Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3141
Multiple vulnerabilities in the web management framework of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to elevate privileges to the level of an Administrator user on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el framework de administración web de Cisco IOS XE Software, podrían permitir a un atacante remoto autenticado con privilegios de solo lectura elevar los privilegios al nivel de un usuario administrador en un dispositivo afectado. Para más información sobre estas vulnerabilidades, consulte la sección Detalles de este aviso. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-webui-priv-esc-K8zvEWM • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3393 – Cisco IOS XE Software IOx Application Hosting Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3393
A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-iox-app-host-mcZcnsBt • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •
CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3404 – Cisco IOS XE Software Consent Token Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3404
A vulnerability in the persistent Telnet/Secure Shell (SSH) 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) with root privileges. 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 persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges. Una vulnerabilidad en la CLI Telnet/Secure Shell (SSH) persistente de Cisco IOS XE Software, podría permitir a un atacante local autenticado obtener acceso de shell en un dispositivo afectado y ejecutar comandos en el sistema operativo (SO) subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ctbypass-7QHAfHkK • CWE-863: Incorrect Authorization •
