The vulnerability exists because the web UI does not properly validate user-supplied input. An attacker could exploit this vulnerability by entering malicious SQL statements in an affected field in the web UI. A successful exploit could allow the attacker to remove the SQL database, which would require the reinstallation of the Connector VM. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
