Description:
Secunia has identified a vulnerability in BRS WebWeaver, which can be exploited by malicious people to conduct Cross-Site Scripting attacks against visitors.
The vulnerability is caused due to a lack of input validation, since the name of a resource requested by a user is included in certain error pages without prior sanitation.
A malicious person can exploit this by constructing a link, which includes arbitrary script code. If a user is tricked into clicking the link or visit a malicious website, the script code will be executed in the user's browser session.
Successful exploitation may result in disclosure of various information (e.g. cookie-based authentication information) associated with the site running BRS WebWeaver, or inclusion of malicious content, which the user thinks is part of the real website.
Example exploiting a "404 Not Found" error page:
http://[victim]/<script>alert(document.domain)</script>
Example exploiting a "403 Access Denied":
http://[victim]/<script>alert(document.domain)</script>AAA..[196]..AAA
The vulnerability has been confirmed in versions 1.0.3 and 1.0.4. However, prior versions may also be affected.
Solution:
Update to version 1.05:
