---

BUGTRAQ  ID: 17861
CVE(CAN) ID: CVE-2006-2270

Jetbox是一款使用php和mysql的内容管理系统。

jetbox/includes/phpdig/includes/config.php文件未经声明便使用了include()函数中的relative_script_path变量，允许攻击者包含远程资源的文件，执行任意代码。

漏洞代码：

if (is_file("$relative_script_path/locales/$phpdig_language-language.php"))
    {include "$relative_script_path/locales/$phpdig_language-language.php";}
else
    {include "$relative_script_path/locales/en-language.php";}
