  Long URL Crashes My Web Server
------------------------------------------------------------------------

SUMMARY

 <http://www.mywebserver.org/us/> MyWebServer is a free personal
peer-to-peer web, file and application server. It allows you and your
associates to access areas of your computer from any location using a
standard web browser, just like any other internet web site. A security
vulnerability in the product allows remote attackers to crash the server.

DETAILS

Vulnerable systems:
 * My Web Server 1.0.2 [Build 03.27.02]

It is possible to crash the webserver with a very long request like this:
http://192.168.0.2/AAA...(approx. Ax994)...AAA

Vendor status:
Marc has informed info@mywebserver.org at 02/10/11 about the problem and
they acknowledged the vulnerability. It would be a good idea the implement
in an upcoming version an input check to cut long requests. Seth Snyder
replied, that he'll add such a feature as soon as possible.
