Description

A vulnerability in the web-based management interface of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to insufficient validation of requests that are sent to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the interface of an affected device. A successful exploit could allow the attacker to obtain the IP addresses that are configured on the internal interfaces of the affected device. There is a workaround that addresses this vulnerability.
