The web interface in Cisco Identity Services Engine (ISE) 1.1(4.1), 1.3(106.146), and 1.3(120.135) does not properly restrict use of IFRAME elements, which makes it easier for remote attackers to conduct clickjacking attacks and unspecified other attacks via a crafted web site, related to a “cross-frame scripting (XFS)” issue, aka Bug ID CSCut04556.
