  • 2Wire 1701HG 3.7.1
  • 2Wire 1701HG 5.29.51
  • 2Wire 1800HW 3.17.5
  • 2Wire 1800HW 3.7.1
  • 2Wire 1800HW 5.29.51
  • 2Wire 2071 Gateway 3.17.5
  • 2Wire 2071 Gateway 3.7.1
  • 2Wire 2071 Gateway 5.29.51


Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com.
