    Cross-site Scripting (XSS)

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

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS). 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.

    Due to improper user input sanitization, the 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.

    How to fix Cross-site Scripting (XSS)?

    Upgrade connect to version 2.8.2 or higher.

    Denial of Service (DoS)

    connect is a high performance middleware framework.

    Affected versions of the package are vulnerable to Denial of Service (DoS) attacks. It is possible to crash the node server by requesting a url with a trailing backslash in the end.

    How to fix Denial of Service (DoS)?

    Upgrade connect to version 2.0.0 or higher.

    Cross-site Scripting (XSS)

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

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS). 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.

    Example

    ~ curl "localhost:3000" -d "_method=<script src=http://nodesecurity.io/xss.js></script>"
Cannot <SCRIPT SRC=HTTP://NODESECURITY.IO/XSS.JS></SCRIPT> /

    Mitigation factors

    Update to version 2.8.2 or disable methodOverride. It is not possible to avoid the vulnerability if you have enabled this middleware in the top of your stack.
