BID: 68195

Background

SENKAS Kolibri Webserver is a free very simple web server for Microsoft Windows that supports serving static web content.

Problem

Kolibri Webserver is vulnerable to a stack buffer overflow as a result of failure to properly validate user-supplied input when handling HTTP GET requests. A remote attacker that supplies an overly long URI in a GET request could potentially execute arbitray code in the context of the Kolibri server.

Resolution

Deploy an alternate web server product or apply a patch when and if it becomes available.
