Name of the Vulnerable Software and Affected Versions: Cisco IOS Software and Cisco IOS XE Software (affected versions not specified)
Description: A vulnerability in the SNMP subsystem 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. The 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.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
