Description:
Some vulnerabilities have been discovered in Sami HTTP Server, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error exists in the way the server handles connections. This can be exploited to cause the server to stop responding to other requests by connecting to the server multiple times in succession (around 2000 connections).
2) An error exists in the processing of certain HTTP requests (e.g. GET, POST, PUT, DELETE). This can be exploited to cause the application to terminate via a specially crafted HTTP request.
The vulnerabilities are confirmed in version 2.0.1. Other versions may also be affected.
Solution:
Restrict access to the web service.
