CVSS: 8.6EPSS: 0%CPEs: 6EXPL: 0CVE-2020-3414 – Cisco IOS XE Software for Cisco 4461 Integrated Services Routers Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3414
A vulnerability in the packet processing of Cisco IOS XE Software for Cisco 4461 Integrated Services Routers could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect processing of IPv4 or IPv6 traffic to or through an affected device. An attacker could exploit this vulnerability by sending IP traffic to or through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento de paquetes de Cisco IOS XE Software para Cisco 4461 Integrated Services Routers, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ISR4461-gKKUROhx • CWE-19: Data Processing Errors CWE-400: Uncontrolled Resource Consumption •
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 •
