An attacker could exploit this vulnerability by sending crafted Modbus traffic through an affected device. A successful exploit could allow the attacker to cause the Snort process to hang, causing traffic inspection to stop.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.", "affected": [ { "vendor": "Cisco", "product": "Cisco Cyber Vision", "defaultStatus": "unknown", "versions": [ { "version": "3.0.0",
