This vulnerability is due to the presence of a static SSH host key. An attacker could exploit this vulnerability by performing a man-in-the-middle attack on an SSH connection to the Umbrella VA. A successful exploit could allow the attacker to learn the administrator credentials, change configurations, or reload the VA. Note: SSH is not enabled by default on the Umbrella VA." } ] }, "exploit": [ { "lang": "eng", "value": "The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
