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:
Updates are available for download from the D-Link web site.
Provided and/or discovered by:
Barnaby Jack, eEye Digital Security.
