A vulnerability in the web-based management interface of Cisco AsyncOS for Secure Email Gateway could allow an authenticated, remote attacker to execute arbitrary system commands on an affected device. This vulnerability is due to insufficient input validation in certain portions of the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. To successfully exploit this vulnerability, an attacker would need at least valid Operator credentials.
