Title: Dino's Webserver Denial of Service Vulnerability

Severity: MODERATE

Description:

Dino's Webserver is a small web server designed for personal use. It is available for Microsoft Window's based machines. Reportedly, Dino's webserver is subject to a denial of service condition.

Submitting multiple GET requests composed of an unusually long string of arbitrary characters, could cause a host's CPU usage to spike to 100% consuming all available system resources.

A restart of the server may be required in order to regain normal functionality.

This issue may be the result of an unchecked buffer. If this is the case, there is a possibility that arbitrary code may be executed on the vulnerable target. However, this has not yet been confirmed.

Affected Products:

  • Funsoft Dino's Webserver 1.0.0
  • Funsoft Dino's Webserver 1.2.0
