PR07-09: XSS on Sun Java System Identity Manager 6.0/7.x "activeControl" parameter

Date Found: 11th June 2007

Vendor Contacted: 18th June 2007

Severity: Medium

BID: 27214

Description:

Sun Java System Identity Manager is vulnerable to XSS within the "activeControl" parameter processed by the "/idm/user/main.jsp" server-side script.

Consequences:

An attacker may be able to cause execution of malicious scripting code in the browser of a user who clicks on a link to Sun Java System Identity Manager.

This type of attack can result in non-persistent defacement of the target site, or the redirection of confidential information to unauthorised third parties.

Note: the victim user needs to be authenticated for this vulnerability to be exploitable.

Proof of concept (PoC):

The provided PoC URL inserts an alert box to simply prove that it's possible to run scripting code within the context of the target domain.

https://target.tld/idm/user/main.jsp?activeControl=";</script>
<script>alert('Running_scripting_within_the_
context_of_'%2bdocument.domain)</script>

Injected payload:

";</script><script>alert('Running_scripting_within_the_context_of_'%2b
document.domain)</script>
