CVE-2020-3422 – Cisco IOS XE Software IP Service Level Agreements Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3422
A vulnerability in the IP Service Level Agreement (SLA) responder feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the IP SLA responder to reuse an existing port, resulting in a denial of service (DoS) condition. The vulnerability exists because the IP SLA responder could consume a port that could be used by another feature. An attacker could exploit this vulnerability by sending specific IP SLA control packets to the IP SLA responder on an affected device. The control packets must include the port number that could be used by another configured feature. A successful exploit could allow the attacker to cause an in-use port to be consumed by the IP SLA responder, impacting the feature that was using the port and resulting in a DoS condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipsla-jw2DJmSv • CWE-371: State Issues •
CVE-2020-3423 – Cisco IOS XE Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3423
A vulnerability in the implementation of the Lua interpreter that is integrated in Cisco IOS XE Software could allow an authenticated, local attacker to execute arbitrary code with root privileges on the underlying Linux operating system (OS) of an affected device. The vulnerability is due to insufficient restrictions on Lua function calls within the context of user-supplied Lua scripts. An attacker with valid administrative credentials could exploit this vulnerability by submitting a malicious Lua script. When this file is processed, an exploitable buffer overflow condition could occur. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying Linux OS of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-lua-rce-7VeJX4f • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2020-3425 – Cisco IOS XE Software Privilege Escalation Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3425
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 •
CVE-2020-3426 – Cisco IOS Software for Cisco Industrial Routers Virtual-LPWA Unauthorized Access Vulnerability
https://notcve.org/view.php?id=CVE-2020-3426
A vulnerability in the implementation of the Low Power, Wide Area (LPWA) subsystem of Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data or cause a denial of service (DoS) condition. The vulnerability is due to a lack of input and validation checking mechanisms for virtual-LPWA (VLPWA) protocol modem messages. An attacker could exploit this vulnerability by supplying crafted packets to an affected device. A successful exploit could allow the attacker to gain unauthorized read access to sensitive data or cause the VLPWA interface of the affected device to shut down, resulting in DoS condition. Una vulnerabilidad en la implementación del subsistema Low Power, Wide Area (LPWA) de Cisco IOS Software para Cisco 800 Series Industrial Integrated Services Routers (Industrial ISRs) y Cisco 1000 Series Connected Grid Routers (CGR1000), podría permitir a un atacante remoto no autenticado conseguir acceso de lectura no autorizado a datos confidenciales o causar una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-lpwa-access-cXsD7PRA • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVE-2020-3428 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family WLAN Local Profiling Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3428
A vulnerability in the WLAN Local Profiling feature of Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect parsing of HTTP packets while performing HTTP-based endpoint device classifications. An attacker could exploit this vulnerability by sending a crafted HTTP packet to an affected device. A successful exploit could cause an affected device to reboot, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad WLAN Local Profiling de Cisco IOS XE Wireless Controller Software para Cisco Catalyst 9000 Family, podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-dclass-dos-VKh9D8k3 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
