Microsoft IIS HTTP GET request with false "Content-Length" field can cause a denial of service
|iis-false-content-length-dos (7691)||Medium Risk|
Microsoft Internet Information Server (IIS) is vulnerable to a denial of service attack. If a remote attacker sends the Web server a specially-crafted HTTP GET request containing a false "Content-Length" header field, the attacker can cause the connection to remain open and become unresponsive while waiting for more data. Opening multiple connections such as this could result in a denial of service against the affected server.
