Description Kurt Seifried 2014-04-25 05:23:59 UTC
The Node Security Project reports:

methodOverride Middleware Reflected Cross-Site Scripting

Connect is a stack of middleware that is executed in order in each request.

The "methodOverride" middleware allows the http post to override the method of 
the request with the value of the "_method" post key or with the header 
"x-http-method-override".

Because the user post input was not checked, req.method could contain any kind 
of value. Because the req.method did not match any common method VERB, connect 
answered with a 404 page containing the "Cannot [method] [url]" content. The 
method was not properly encoded for output in the browser.

===

nodejs-connect 2.8.0 is vulnerable to this, an incomplete fix was applied, 
version 2.8.1 is also vulnerable, versions 2.8.2 and later have been corrected.

Please note that the first attempt to fix this was not complete and requires a
second fix:

First fix: https://github.com/senchalabs/connect/commit/277e5aad6a95d00f55571a9a0e11f2fa190d8135
Second fix: https://github.com/senchalabs/connect/commit/126187c4e12162e231b87350740045e5bb06e93a

The incomplete fix for this resulted in a second vulnerability referred to as 
CVE-2013-7371.
