Description:
A vulnerability has been reported in Savant Web Server, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when handling certain HTTP GET requests. This can be exploited by sending a specially crafted request, which causes the web service to keep redirecting to the default page, hence causing an infinate loop until finally crashing.
Example:
http://[victim]/%x
The vulnerability has been reported in version 3.1. However, other versions may also be affected.
Solution:
Filter malicious requests in a HTTP proxy or firewall with URL filtering capabilities.
