CVSS: 8.6EPSS: 0%CPEs: 38EXPL: 0CVE-2020-3421 – Cisco IOS XE Software Zone-Based Firewall Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3421
Multiple vulnerabilities in the Zone-Based Firewall feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload or stop forwarding traffic through the firewall. The vulnerabilities are due to incomplete handling of Layer 4 packets through the device. An attacker could exploit these vulnerabilities by sending a certain sequence of traffic patterns through the device. A successful exploit could allow the attacker to cause the device to reload or stop forwarding traffic through the firewall, resulting in a denial of service. For more information about these vulnerabilities, see the Details section of this advisory. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-zbfw-94ckG4G • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 8.6EPSS: 0%CPEs: 30EXPL: 0CVE-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 •
CVSS: 7.2EPSS: 0%CPEs: 26EXPL: 0CVE-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 •
CVSS: 8.8EPSS: 0%CPEs: 216EXPL: 0CVE-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 •
CVSS: 7.4EPSS: 0%CPEs: 74EXPL: 0CVE-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 •
