Description

Nick Simicich has reported a security issue in WRT54G, which potentially can be exploited by malicious people to gain knowledge of certain sensitive information.

The security issue is caused due to all routers being loaded with the same certificate and SSL private key. A user with knowledge with the private key can potentially decrypt router management traffic captured from the network.


Solution
The vendor will reportedly use unique SSL private keys with a self-signed certificate for each router in new software versions.
