Description

A vulnerability in the web-based management interface of Cisco Email Security Appliance (ESA), Cisco Secure Email and Web Manager, and Cisco Secure Web Appliance, formerly known as Cisco Web Security Appliance (WSA), could allow an authenticated, remote attacker to retrieve sensitive information from an affected device, including user credentials.
