Description:
Microsoft IIS ships with Front Page Server Extensions (FPSE) which
enables administrators remote and local web page and content
management. Browse - time support is another feature within FPSE
which provides users with functional web applications.
Due to the way FPSE handles the processing of web forms, IIS is
subject to a denial of service. By supplying malformed data to one of the
FPSE functions IIS will stop responding. A restart of the service is
required in order to gain normal functionality.
It should be noted that the victim only requires to have FPSE installed
on the web server to be vulnerable.
