Version Summary: Cisco Web Security Appliance contains a vulnerability that
could allow an unauthenticated, remote attacker to conduct cross-site
scripting attacks. Updates are not available.
A vulnerability in the Web Tracking Report page of the Cisco Web Security
Appliance (WSA) could allow an unauthenticated, remote attacker to perform a
cross-site scripting (XSS) attack against the user of the web interface.
The vulnerability is due to improper validation of user-supplied input in a

user to a malicious site and use misleading language or instructions to
persuade the user to follow the provided link.
Cisco has released bug ID CSCuu16008 for registered users, which contains
additional details and an up-to-date list of affected product versions.
An unauthenticated, remote attacker could exploit this vulnerability to
execute arbitrary code in the user's browser session in the context of the

sensitive browser-based information such as authentication cookies and
recently submitted data.
The vulnerability is due to insufficient validation of user-supplied input
submitted to the Web Tracking Report page of an affected device.
An unauthenticated, remote attacker could exploit this vulnerability by
