Abstract
A response used in FIM SAML 2.0 protocol could potentially contain unencoded
data provided by an untrusted source. An attacker could potentially use this
to initiate a cross site scripting attack.
Content
VULNERABILITY DETAILS
CVE ID: CVE-2013-0582
DESCRIPTION:
All data sent to FIM by untrusted clients is normally URL encoded to prevent
cross-site scripting attacks. It is possible to construct a URL which, if
requested, could result in a corresponding HTTP response that could contain
unencoded data provided in the URL. If an attacker were to construct this URL
and induce a victim to request it, the attacker could include a script in the
URL that could be executed on the victim's browser.
The attack does not require that the attacker authenticate. The attack does not
require local network access, but specialized knowledge and techniques are
required. An exploit will not impact accessibility of system resources, but
both the confidentiality of information and the integrity of transmitted data
could be compromised.
