Description

eEye Digital Security has reported a vulnerability in various D-Link routers, which can be exploited by malicious people to compromise a vulnerable network device.

The vulnerability is caused due to a boundary error in the UPnP service when processing "M-SEARCH" requests. This can be exploited to cause a stack-based buffer overflow by sending an "M-SEARCH" request with an overly long string (about 800 bytes) to port 1900/UDP.

Successful exploitation allows execution of arbitrary code.


Solution
