BackupPC "num" Cross-Site Scripting Vulnerability


Description   A vulnerability has been discovered in BackupPC, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "num" parameter in index.cgi (when "action" is set to "browse" and "host" is set to a valid host) is not properly sanitised before being returned to the user in Browse.pm. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
