The underlying weakness: Selection of Less-Secure Algorithm During Negotiation
A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used in a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.
