Summary
IBM Business Process Manager 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: IBM Business Process Manager 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.
