CVE-2017-11195 Information

Description

Pulse Connect Secure 8.3R1 has Reflected XSS in launchHelp.cgi. The helpLaunchPage parameter is reflected in an IFRAME element if the value contains two quotes. It properly sanitizes quotes and tags so one cannot simply close the src with a quote and inject after that. However an attacker can use javascript: or data: to abuse this.
