  script_tag(name:"insight", value:"The following flaws exist:

  - An user controlled input is not sufficiently sanitized and can be exploit
    by an attacker to get sensitive information.

  - By sending GET request to the following URI's with 'filename=' as a
    parameter, an attacker can trigger the vulnerabilities:

  - /webfolder/download_file1.php

  - down_data.php

  - download_file.php

  - mobile/download_file1.php

  - By sending GET request to '/mobile/download_file2.php' an attacker can get
    sensitive information.

  - By sending a GET request to 'root_exec_cmd()' with user controlled '$cmd'
    variable input an attacker can execute arbitrary commands.

  - Accessing 'webfolder/config/config.php' will disclose the PHP configuration.

  - A default account exists: Username: guest, Password: guest09#$");
