Date Discovered January 6, 2003
Description The Longshine LCS-883R-AC-B device will allow tftp connections. An attacker can exploit this vulnerability to connect via tftp to the access point and download the configuration file without any authentication.
The configuration file contains sensitive information including the administrator password and WEP keys.
** The D-Link DI-614+ product, reportedly based on the Longshine device, appears to be vulnerable to this issue however, only some files were accessible.
- D-Link DI-614+ 2.0.0
- Longshine Technologies LCS-883R-AC-B
Block external access at the network boundary, unless external parties require service. If possible, configure the access point to prevent TFTP access. This may effectively prevent exploitation of this vulnerability.
Block external access at the network boundary, unless external parties require service. It may be possible to mitigate this issue by placing a firewall, configured to deny tftp requests, between the vulnerable device and the untrusted network.
Modify default configuration files to disable any unwanted behavior.
Modify the access point's configuration settings to change all default passwords, SSID values and other pertinent information.
Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or are aware of more recent information, please mail us at: email@example.com <mailto:firstname.lastname@example.org>.
