TITLE:
Mono ASP.net Cross-Site Scripting

SECUNIA ADVISORY ID:
SA31338

VERIFY ADVISORY:
http://secunia.com/advisories/31338/

CRITICAL:
Not critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Mono 1.x
http://secunia.com/product/4673/

DESCRIPTION:
Dean Brettle has reported some security issues in Mono, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

The security issues are caused due to Mono's ASP.net implementation
not properly sanitising certain attributes (e.g. "HtmlSelect.Value",
"HtmlSelect.Text", and the "action" attribute of the "<form>"
element). This can be exploited to execute arbitrary HTML and script
code in a user's browser session in context of an affected site.

The security issues are reported in version 1.9.1. Other versions may
also be affected.

SOLUTION:
Fixed in the SVN repository.

PROVIDED AND/OR DISCOVERED BY:
Dean Brettle
