Severity ?
7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
Summary
A vulnerability in the SNMP subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause a DoS condition on an affected device. This vulnerability is due to improper error handling when parsing SNMP requests. An attacker could exploit this vulnerability by sending a crafted SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition.  This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMP v2c or earlier, the attacker must know a valid read-write or read-only SNMP community string for the affected system. To exploit this vulnerability through SNMP v3, the attacker must have valid SNMP user credentials for the affected system.

         value: "Una vulnerabilidad en el subsistema SNMP de Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante remoto autenticado provoque una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a una gestión inadecuada de errores al analizar las solicitudes SNMP. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud SNMP manipulada a un dispositivo afectado. Una explotación exitosa podría permitir que el atacante haga que el dispositivo se recargue inesperadamente, lo que da como resultado una condición de denegación de servicio (DoS). Esta vulnerabilidad afecta a las versiones 1, 2c y 3 de SNMP. Para aprovechar esta vulnerabilidad a través de SNMP v2c o anterior, el atacante debe conocer una cadena de comunidad SNMP válida de lectura y escritura o de solo lectura para el sistema afectado. Para aprovechar esta vulnerabilidad a través de SNMP v3, el atacante debe tener credenciales de usuario SNMP válidas para el sistema afectado.",
