Description:
An input validation vulnerability was reported in Mailreader. A remote user can conduct cross-site scripting attacks.
The software does not properly filter HTML code from e-mail messages when MIME type 'text/enriched' or 'text/richtext' messages. A remote user can send a specially crafted e-mail message that, when viewed by a target user with mailreader, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Mailreader 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.
Ulf Harnhammar from the Debian Security Audit Project discovered this vulnerability.
