Helm Web Hosting Control Panel XSS Vulnerabilities

r0t has reported some vulnerabilities in Helm Web Hosting Control Panel, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "showOption" parameter in interfaces/standard/domain.asp and to the "Folder" and "StartPath" parameters in interfaces/standard/FileManager.asp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
