XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl.
XAMPP suffers from multiple XSS issues in several scripts that use the 'PHP_SELF' variable. The vulnerabilities can be triggered in the 'xamppsecurity.php', 'cds.php' and 'perlinfo.pl' because there isn't any filtering to the mentioned variable in the affected scripts. Attackers can exploit these weaknesses to execute arbitrary HTML and script code in a user's browser session.
