Description: A vulnerability was reported in Citrix XenServer. A remote user can conduct cross-site scripting attacks.
The XenAPI HTTP interfaces does not properly filter HTML code from user-supplied input before displaying the input. A remote user
can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the
target user's browser. The code will originate from the site running the Citrix XenServer software and will run in the security
context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies),
if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on
the site acting as the target user.
Versions 4.0 and prior versions are not affected.
TEPCO from Japan reported this vulnerability.
