Description

Certain versions of Cisco IOS contain embedded community names which could allow a remote attacker to view and/or modify SNMP MIB variables. This could lead to a denial-of-service attack or total system compromise. The first embedded community name "ILMI" is a read-write community name which allows access to the MIB-II System MIB and various ATM related MIBS. A remote user can modify SNMP variables including the system name, contact, and location, and several ATM interface variables.The second embedded community name "cable-docsis" is a read-write community string which was introduced as part of the support for the DOCSIS cable-industry standard. It allows a remote user to modify or view any SNMP variable on the affected system, including being able to retrieve the system configuration.This signature is associated with two different yet related Cisco PSIRT advisories. Please consult the related vulnerabilities for more information.
