A vulnerability in the web-based management interface of Cisco Email Security Appliance, Cisco Secure Email and Web Manager and Cisco Secure Web Appliance could allow an authenticated, remote attacker to elevate privileges on an affected system. The attacker needs valid credentials to exploit this vulnerability.

This vulnerability is due to the use of a hardcoded value to encrypt a token used for certain APIs calls . An attacker could exploit this vulnerability by authenticating to the device and sending a crafted HTTP request. A successful exploit could allow the attacker to impersonate another valid user and execute commands with the privileges of that user account.
