Zone-h Security Team reported a vulnerability in 'ChitChat.NET'. A remote user can conduct cross-site scripting attacks.|
It is reported that the software does not properly filter HTML code from the 'Name' and 'Topic Title' fields. A remote user can insert some specially crafted text into either or both of those fields as part of a chat session. Then, when the target user views the message, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running the ChitChat.NET 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.
