Linksys EtherFast BEFVP41 Cable/DSL VPN Router weak key encryption
|linksys-etherfast-weak-encryption (8397)||Low Risk|
Linksys EtherFast Cable/DSL VPN Router incorrectly truncates the key length for manually entered keys. If a user enters a 3DES key and MD5 authentication key, the keys are truncated to 23 bytes and 19 bytes respectively, which are both below the supposed allowed length. This vulnerability results in weaker than expected encryption.
No remedy available as of February 1, 2014.
