Description:
Two vulnerabilities were reported in Samba in the Samba Web Administration Tool. A remote user can conduct cross-site request forgery attacks. A remote user can conduct cross-site scripting attacks.
The 'user' field of the 'Change Password' function in the Samba Web Administration Tool (SWAT) does not properly filter HTML code from user-supplied input before displaying the input [CVE-2011-2694]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Samba SWAT 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.
The Samba SWAT does not properly validate requests. A remote user can conduct cross-site request forgery attacks [CVE-2011-2522].

Impact:
A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Samba SWAT software, 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.
