{"schemaVersion":3,"id":"CVE-2018-0156","aliases":[],"status":"published","duplicateOf":null,"title":"Cisco IOS Software and Cisco IOS XE Software Smart Install Denial-of-Service Vulnerability","description":"A vulnerability in the Smart Install feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of packet data. An attacker could exploit this vulnerability by sending a crafted packet to an affected device on TCP port 4786. Only Smart Install client switches are affected. Cisco devices that are configured as a Smart Install director are not affected by this vulnerability.
