Description:
Some vulnerabilities have been discovered in Toast Forums, which can be exploited by malicious people to conduct cross-site scripting attacks and script insertion attacks.
1) Some input isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Examples:
http://[host]/toast.asp?action=posts&sub=search&fid-1&author=[code]
http://[host]/toast.asp?action=posts&sub=search&fid-1&author=r0t&subject=[code]
http://[host]/toast.asp?action=posts&sub=search&fid-1&author=r0t&subject=&message=[code]
http://[host]/toast.asp?action=posts&sub=search&fid-1&author=r0t&subject=&message=&dayprune=[code]
2) Input passed to the "message" form field parameter when posting a message or a reply is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is then executed in a user's browser session in context of an affected site when malicious data is viewed.
Successful exploitation requires that certain HTML tags (e.g. <img>) are allowed.
The vulnerabilities are confirmed in version 1.6. Other versions may also be affected.
Solution:
Update to version 1.646, which fixes #2 and some affected input in #1. Edit the source code to ensure that input is properly sanitised.
