Input passed to the "user" parameter in upload.cgi (when "ac" is set to "login") 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. The vulnerability is reported in version 1.1. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised.
