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.
