Description:
Linksys routers suffers a remotely exploitable Denial of Service vulnerability.
By sending a password which is thousands of characters long it is possible to cause a Denial of Service.
This may only be exploited from remote if management is enabled on the remote interface.
Known affected products are:
BEFW11S4, BEFSR11, BEFSR41 and BEFSRU31
Solution:
Linksys firmware 1.43.3 is not vulnerable.
A workaround is to disable management on the remote interface and limit access on the internet network.
