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: 8.6EPSS: 0%CPEs: 260EXPL: 0CVE-2020-3226 – Cisco IOS and IOS XE Software Session Initiation Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3226
A vulnerability in the Session Initiation Protocol (SIP) library of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on received SIP messages. An attacker could exploit this vulnerability by sending crafted SIP messages to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service condition. Una vulnerabilidad en la biblioteca Session Initiation Protocol (SIP) de Cisco IOS Software y Cisco IOS XE Software, podría permitir que un atacante remoto no autenticado desencadene una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sip-Cv28sQw2 • CWE-20: Improper Input Validation •
CVSS: 7.2EPSS: 0%CPEs: 224EXPL: 0CVE-2020-3215 – Cisco IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3215
A vulnerability in the Virtual Services Container of Cisco IOS XE Software could allow an authenticated, local attacker to gain root-level privileges on an affected device. The vulnerability is due to insufficient validation of a user-supplied open virtual appliance (OVA). An attacker could exploit this vulnerability by installing a malicious OVA on an affected device. Una vulnerabilidad en el Virtual Services Container de Cisco IOS XE Software, podría permitir a un atacante local autenticado conseguir privilegios de nivel root sobre un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de un open virtual appliance (OVA) suministrado por el usuario. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-priv-esc1-OKMKFRhV • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.2EPSS: 0%CPEs: 192EXPL: 0CVE-2020-3213 – Cisco IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3213
A vulnerability in the ROMMON of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to those of the root user of the underlying operating system. The vulnerability is due to the ROMMON allowing for special parameters to be passed to the device at initial boot up. An attacker could exploit this vulnerability by sending parameters to the device at initial boot up. An exploit could allow the attacker to elevate from a Priv15 user to the root user and execute arbitrary commands with the privileges of the root user. Una vulnerabilidad en el ROMMON de Cisco IOS XE Software, podría permitir a un atacante local autenticado elevar los privilegios a los del usuario root del sistema operativo subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-priv-esc3-GMgnGCHx • CWE-264: Permissions, Privileges, and Access Controls •
