A recent firmware release, specifically FutureSmart 3.9.10, altered the cipher suite prioritization list placing the 3DES cipher into the HIGH prioritization cipher list. By default, this version (3.9.10) enables 3DES which is a “weak” cipher and may potentially allow the “Sweet32” vulnerability to be exploited.

Update firmware. Ensure cipher suite configuration is set to HIGH.
