CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-16009 – Cisco IOS and Cisco IOS XE Software Web UI Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-16009
A vulnerability in the web UI of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or reload an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-ios-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 7.7EPSS: 0%CPEs: 1198EXPL: 0CVE-2020-3200 – Cisco IOS and IOS XE Software Secure Shell Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3200
A vulnerability in the Secure Shell (SSH) server code of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. The vulnerability is due to an internal state not being represented correctly in the SSH state machine, which leads to an unexpected behavior. An attacker could exploit this vulnerability by creating an SSH connection to an affected device and using a specific traffic pattern that causes an error condition within that connection. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el código del servidor Secure Shell (SSH) de Cisco IOS Software y el Cisco IOS XE Software, podría permitir a un atacante remoto autenticado causar una recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssh-dos-Un22sd2A • CWE-371: State Issues CWE-436: Interpretation Conflict •
CVSS: 8.6EPSS: 0%CPEs: 490EXPL: 0CVE-2020-3228 – Cisco IOS, IOS XE, and NX-OS Software Security Group Tag Exchange Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3228
A vulnerability in Security Group Tag Exchange Protocol (SXP) in Cisco IOS Software, Cisco IOS XE Software, and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because crafted SXP packets are mishandled. An attacker could exploit this vulnerability by sending specifically crafted SXP packets to the affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en Security Group Tag Exchange Protocol (SXP) en Cisco IOS Software, Cisco IOS XE Software y Cisco NX-OS Software, podría permitir a un atacante remoto no autenticado causar que el dispositivo afectado se vuelva a cargar, resultando en una condición denegación de servicio (DoS ). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sxp-68TEVzR • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 792EXPL: 0CVE-2020-3230 – Cisco IOS and IOS XE Software Internet Key Exchange Version 2 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3230
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) implementation in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to prevent IKEv2 from establishing new security associations. The vulnerability is due to incorrect handling of crafted IKEv2 SA-Init packets. An attacker could exploit this vulnerability by sending crafted IKEv2 SA-Init packets to the affected device. An exploit could allow the attacker to cause the affected device to reach the maximum incoming negotiation limits and prevent further IKEv2 security associations from being formed. Una vulnerabilidad en la implementación de Internet Key Exchange Versión 2 (IKEv2) en Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado impedir que IKEv2 establezca nuevas asociaciones de seguridad. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev2-9p23Jj2a • CWE-20: Improper Input Validation •
CVSS: 8.8EPSS: 0%CPEs: 679EXPL: 0CVE-2020-3217 – Cisco IOS, IOS XE, IOS XR, and NX-OS Software One Platform Kit Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3217
A vulnerability in the Topology Discovery Service of Cisco One Platform Kit (onePK) in Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient length restrictions when the onePK Topology Discovery Service parses Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol message to an affected device. An exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges, or to cause a process crash, which could result in a reload of the device and cause a DoS condition. Una vulnerabilidad en el Topology Discovery Service de Cisco One Platform Kit (onePK) en Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, y Cisco NX-OS Software, podría permitir a un atacante adyacente no autenticado ejecutar código arbitrario o causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-nxos-onepk-rce-6Hhyt4dC • CWE-20: Improper Input Validation •
