Descriptions

A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS Software running on certain models of Cisco Catalyst Switches could allow an authenticated, remote attacker to cause a denial of service (DoS) condition, aka a GET MIB Object ID Denial of Service Vulnerability. The vulnerability is due to a condition that could occur when the affected software processes an SNMP read request that contains a request for the ciscoFlashMIB object ID (OID). An attacker could trigger this vulnerability by issuing an SNMP GET request for the ciscoFlashMIB OID on an affected device. A successful exploit could cause the affected device to restart due to a SYS-3-CPUHOG. This vulnerability affects the following Cisco devices if they are running a vulnerable release of Cisco IOS Software and are configured to use SNMP Version 2 (SNMPv2) or SNMP Version 3 (SNMPv3): Cisco Catalyst 2960-L Series Switches, Cisco Catalyst Digital Building Series Switches 8P, Cisco Catalyst Digital Building Series Switches 8U. Cisco Bug IDs: CSCvd89541.

Una vulnerabilidad en el subsistema Simple Network Management Protocol (SNMP) de Cisco IOS Software que ejecuta determinados modelos de Cisco Catalyst Switches podría permitir que un atacante remoto autenticado provoque una denegación de servicio (DoS). Esto también se conoce como vulnerabilidad GET MIB Object ID Denial of Service. Esta vulnerabilidad se debe a una condición que podría ocurrir cuando el software afectado procesa una petición de lectura SNMP que contiene una petición para el ID de objeto (OID) de ciscoFlashMIB. Un atacante podría desencadenar esta vulnerabilidad enviando una petición SNMP GET para el OID de ciscoFlashMIB en un dispositivo afectado Un exploit con éxito podría provocar que el dispositivo afectado se reinicie debido a un SYS-3-CPUHOG. Esta vulnerabilidad afecta a los siguientes dispositivos Cisco en caso de que ejecuten una distribución vulnerable de Cisco IOS Software y que estén configurados para utilizar SNMP Version 2 (SNMPv2) o SNMP Version 3 (SNMPv3): Cisco Catalyst 2960-L Series Switches, Cisco Catalyst Digital Building Series Switches 8P, Cisco Catalyst Digital Building Series Switches 8U. Cisco Bug IDs: CSCvd89541.
