* Crawler endless loop (CVE-2010-3899)
|
|
|
|
The crawler has no recursion depth limit. A site with dynamic parameter manipulation can
|
|
cause an endless loop. This loop will block the crawler thread and use permanent server
|
|
resources. Too many blocks can lead to a denial of service. The same site will be
|
|
indexed more times and the search results will display the same site many times. This
|
|
can be abused for spamming the search results.
|
|
|
|
|
|
Exploit to test the endless loop:
|
|
/* loop.php */
|
|
<?php
|
|
$numb = rand();
|
|
echo $numb.'<br><a href="loop.php?value='.$numb.'">click me</a>';
|
|
?>
|
