Blacklist Test

This little script helps to check a text against the blacklist - nice for debugging it.

<?php
require_once("inc/init.php");
 
$text = $_POST['text'];
 
function checkit($file,$text){
    $blockfile = (array) @file(DOKU_CONF.$file);
    $ln=0;
    $text = preg_replace('!(\b)(www\.[\w.:?\-;,]+?\.[\w.:?\-;,]+?[\w/\#~:.?+=&%@\!\-.:?\-;,]+?)([.:?\-;,]*[^\w/\#~:.?+=&%@\!\-.:?\-;,])!i','\1http://\2 \2\3',$text);
    foreach($blockfile as $block){
        $i++;
        $block = preg_replace('/#.*$/','',$block);
        $block = trim($block);
        if(empty($block)) continue;
        if(preg_match('#('.$block.')#si',$text,$matches)){
            $pos = strpos($text,$matches[0]);
            $s = max(0,$pos - 15);
            $l = strlen($matches[0])+30;
            $snip = substr($text,$s,$l);
            print '<li>';
            print "$file line $i: ";
            print htmlspecialchars($block);
            print "<br /><pre>".htmlspecialchars($snip)."</pre>";
            print '</li>';
        }
    }
}
 
header('Content-Type: text/html; charset=utf-8');
?>
<html>
<head><title>Spamcheck</title></head>
<body>
<form method="post" accept-charset="utf-8">
<textarea name="text" cols="50" rows="10"><?php echo htmlspecialchars($text)?></textarea><br />
<input type="submit" />
</form>
<ul>
<?php
if($text){
  checkit('wordblock.conf',$text);
  checkit('wordblock.local.conf',$text);
}
?>
</ul>
</body>
</html>

Logging of blocked Attacks

This small change makes it possible to log blocked attacks in \DATA\meta\wordblock.log and can also be used for block lists debugging.
But need a modification of a original DokuWiki file.

File: \inc\common.php

Search Line:

    if(preg_match('#('.join('|',$re).')#si',$text, $match=array())) {
      return true;
    }

Change:

    if(preg_match('#('.join('|',$re).')#si',$text, $match=array())) {
 
      preg_match('#('.join('|',$re).')#si',$text, $match);
      io_saveFile($conf['metadir'].'/wordblock.log', date($conf['dformat'])."\t".$match[0]."\t".$ID.$_SERVER['REMOTE_USER']."\t".$_SERVER['REMOTE_ADDR'].":".$_SERVER['SERVER_PORT']."\t".gethostbyaddr($_SERVER['REMOTE_ADDR'])."\t".$_SERVER['HTTP_USER_AGENT']."\n",true);
 
      return true;
    }
