Vulnerability Summary

A vulnerability in the IIS Server component of Microsoft Windows could allow an unauthenticated, remote malicious user to cause a denial of service (DoS) condition on a targeted system. The vulnerability exists because the affected software improperly filters requests when the optional request filtering feature is enabled. An attacker could exploit the vulnerability by sending a request that submits malicious input to a page configured with request filtering. A successful exploit could allow the malicious user to cause the system to stop responding, leading to a DoS condition. Microsoft confirmed the vulnerability and released software updates.
