Yunus Emre Yilmaz has reported two vulnerabilities in PeHePe Membership Management System, which can be exploited by malicious people to conduct cross-site scripting attacks and compromise a vulnerable system.

1) Input passed to the "kuladi" parameter in sol_menu.php isn't 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.

Example:
http://[host]/sol_menu.php?kuladi=[code]

2) Input passed to the "uye_klasor" parameter in sol_menu.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local and remote resources.

Example:
http://[host]/sol_menu.php?uye_klasor=[file]&misafir[]=UYE_SEVIYE

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been reported in version 3.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
