CWE-79
Summary
A vulnerability in the web-based management interface of Cisco Web Security
Appliance (WSA) could allow an unauthenticated, remote attacker to conduct a
reflected cross-site scripting (XSS) attack against a user of the web-based
management interface of an affected device.
The vulnerability is due to insufficient validation of user-supplied input by
the web-based management interface of an affected device. An attacker could
exploit this vulnerability by persuading a user of the interface to click a
crafted link. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the interface or allow the attacker to
access sensitive browser-based information.
There are no workarounds that address this vulnerability.
