Description:
Doz has reported some vulnerabilities in InstantForum.NET, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "Username" and "Update" parameters in Members1.aspx and to the "SessionID" parameter in Logon.aspx is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
