Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, the Cisco Web Security Appliance (WSA) is affected by an information disclosure vulnerability in the web-based management interface of Cisco AsyncOS software due to the use of an insecure method to mask certain passwords on the web-based management interface. An authenticated, remote attacker could exploit this by looking at the raw HTML code that is received from the interface. A successful exploit could allow an attacker to obtain some of the passwords configured throughout the interface.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
