Cisco Email Security Appliance Information Disclosure (cisco-sa-esa-wsa-sma-info-gY2AEz2H)

medium Nessus Plugin ID 149844


The remote device is missing a vendor-supplied security patch


A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability exists because confidential information is included in HTTP requests that are exchanged between the user and the device. An attacker could exploit this vulnerability by looking at the raw HTTP requests that are sent to the interface. A successful exploit could allow the attacker to obtain some of the passwords that are configured throughout the interface.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
