Summary

WebSphere Lombardi Edition uses a mechanism to silently login users who have 
previously authenticated themselves. This mechanism is vulnerable to 
cross-site scripting attacks.

Vulnerability Details

CVE ID: CVE-2014-6101

DESCRIPTION: WebSphere Lombardi Edition is vulnerable to cross-site scripting,
which is caused by the improper validation of user-supplied input. A remote 
attacker might exploit this vulnerability using a specially crafted URL to 
execute a script in a user's web browser within the security context of the 
hosting web site after the URL is clicked. An attacker might use this 
vulnerability to steal the user's cookie-based authentication credentials.

Workarounds and Mitigations

The attack requires a user to access a malicious URL that the attacker has 
constructed for this purpose. Advise your users not to click links of unknown
or untrusted origins.
