SSH and utilizing TFTP to pull down a malicious binary that is designed to
exploit the insufficient validation issue of the affected System Calls. He ran
this from the user context on the device which performed the exploit. The
caveats of this particular issue are that an attacker would need to have Authenticated
Access either via SSH (Which would need to be enabled, it is not enabled by
default), or local access via the Serial port. The attacker would also need to
be able to point the device at an attacker-controlled TFTP server to retrieve
the payload.</span></p><p><span style="font-size:10.5pt;font-family:Calibri,sans-serif">YMMV</span></p><span><font color="#888888"><p><span style="font-size:10.5pt;font-family:Calibri,sans-serif">Scott</span></p>

thinking about once management sees the following article?<br>
