Default SSH Key Found in Many Cisco Security Appliances | Threatpost

Many Cisco security appliances contain default, authorized SSH keys that can allow an attacker to connect to an appliance and take almost any action he chooses. The company said that all of its Web Security Virtual Appliances, Email Security Virtual Appliances, and Content Security Management Virtual Appliances are affected by the vulnerability.

This bug is about as serious as they come for enterprises. An attacker who is able to discover the default SSH key would have virtually free reign on vulnerable boxes, which, given Cisco’s market share and presence in the enterprise worldwide, is likely a high number. The default key apparently was inserted into the software for support reasons.
