      PhpDig Remote Command Execution
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.phpdig.net/> PhpDig is "an HTTP spider/search engine written
    in PHP with a mySQL database in backend. PhpDig builds a glossary with the
    keywords found in indexed pages. On a search query, it displays a result
    page with documents which contain the search keys, ranked by occurrence".
    A vulnerability in PhpDig allows remote attackers to include an external
    PHP file that will be later executed.

    DETAILS

    Vulnerable Systems:
     * PhpDig version 1.6.x and prior

    Due to a vulnerability in the product a remote attacker can inject a URL
    in $relative_script_path and obtain command execution with the web
    server's privileges (usually nobody).

    From the file ./include/config.php:
    //includes language file
    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";}

    //includes of libraries
    include "$relative_script_path/libs/phpdig_functions.php";
    include "$relative_script_path/libs/function_phpdig_form.php";
    include "$relative_script_path/libs/mysql_functions.php";

    Workarounds:
    Several workarounds can be used:

     * Patching .htaccess in ./includes
     * Turning PHP globals off (Default in PHP > 4.2).
     * An unofficial patch for config.php which can be found at
    <http://www.kernelpanik.org/code/kernelpanik/phpdig.zip>
