Descriptions

Multiple vulnerabilities in the implementation of the Common Industrial Protocol (CIP) feature in Cisco IOS 12.4 through 15.6 could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to the improper parsing of crafted CIP packets destined to an affected device. An attacker could exploit these vulnerabilities by sending crafted CIP packets to be processed by an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvc43709.

Múltiples vulnerabilidades en la implementación de una característica CIP (Common Industrial Protocol) en Cisco IOS desde la versión 12.4 hasta la 15.6 podrían permitir que un atacante remoto sin autenticar haga que el dispositivo afectado se reinicie, provocando una denegación de servicio (DoS) en consecuencia. Estas vulnerabilidades se deben a un análisis sintáctico incorrecto de los paquetes CIP manipulados destinados al dispositivo afectado. Un atacante podría explotar estas vulnerabilidades enviando paquetes CIP manipulados para que los procese el dispositivo afectado. Si se explota con éxito, podría permitir que el atacante consiga que el dispositivo afectado se reinicie, provocando una denegación de servicio. Cisco Bug IDs: CSCvc43709.

There is a vulnerability in the implementation of the Common Industrial Protocol (CIP) feature in Cisco IOS could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service.
