C1c4Tr1Z has discovered some vulnerabilities in @Mail WebMail, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "file" and "HelpFile" parameters in parse.php, the "start" and "Folder" parameters in showmail.php, and to the "abookview" parameter in abook.php 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 a vulnerable site.
The vulnerabilities are confirmed in version 5.05 on Windows using the "Simple (Any browser)" interface.
Solution: Filter malicious characters and character sequences in a proxy
