Description: A vulnerability was reported in Tomcat Host Manager. A remote user can conduct cross-site scripting attacks.
The Host Manager Servlet does not properly filter HTML code from user-supplied input before displaying the input. A remote user
can create a specially crafted request that, when loaded by a target user, will cause arbitrary scripting code to be executed by
the target user's browser. The code will originate from the site running the Tomcat Host Manager software and will run in the security
context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies),
if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on
the site acting as the target user.
A demonstration exploit is provided:
<form action="http://[target]:8080/host-manager/html/add"
method="get">
<input type="hidden" NAME='name' VALUE="aaa">
<input type="hidden" NAME='aliases' VALUE="<script>alert()</script>">
<input
type="submit">
</form>
The NTT OSS CENTER and JPCERT/CC reported this vulnerability.

Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
Tomcat Host Manager software, access data recently submitted by the target user via web form to the site, or take actions on the
site acting as the target user.
|
Solution: The vendor has issued a fixed version (6.0.14).
