Signature Detail

HTTP: Microsoft HTTP Services Chunked Encoding Integer Overflow

This signature detects attempts to exploit a known flaw in Microsoft HTTP Services. An integer overflow vulnerability has been reported in Microsoft Windows HTTP Services. The flaw is due to improper validation of parameters returned by a remote Web server. An attacker can persuade the target user or a service running on the target system to connect to a malicious Web Sever to exploit this vulnerability. Successful attack could allow for arbitrary code execution and complete control of the targeted system. In an attack scenario, where arbitrary code is injected and executed on the target system, the attacker could install applications; access, modify, and delete data; or create new accounts with privileges of the user or service that connected to the malicious Web server. Unsuccessful attacks could result in the termination of any Windows service or third party application using HTTP services.

Extended Description

Microsoft Windows HTTP Services (WinHTTP) is prone to a remote code-execution vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the user running the application. Successful exploits will compromise an affected application and possibly the computer. Failed attacks will cause denial-of-service conditions.
