cisco-sa-20180606-webex-xss1: Cisco WebEx Cross-Site Scripting Vulnerability
A vulnerability in the web framework of the https://try.webex.com page of Cisco WebEx could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters that are passed to the affected software via the HTTP GET and HTTP POST methods. An attacker who can convince a user to follow an attacker-supplied link could execute arbitrary script or HTML code in the user’s browser in the context of an affected site.
There are no workarounds that address this vulnerability.
