CWE-79

Summary
 
A vulnerability in Cisco WebEx Meeting Center could allow an
unauthenticated, remote attacker to conduct a cross-site scripting
(XSS) attack against a user of an affected system.

The vulnerability is due to insufficient input validation of some
parameters that are passed to the web server of the affected system.
An attacker could exploit this vulnerability by convincing a user to
follow a malicious link or by intercepting a user request and
injecting malicious code into the request. A successful exploit could
allow the attacker to execute arbitrary script code in the context of
the affected web interface or allow the attacker to access sensitive
browser-based information.

There are no workarounds that address this vulnerability.
