Subject [jira] [Commented] (CXF-1636) Have WSS4J in/out interceptors require nonces and timestamps when using UsernameTokens?

Yep correct.

Ok, so you're happy with the original design? If not specified, it's false for client and
true for recipient. Setting it to false disables it altogether, setting it to true enables
it for both message initiator and recipient.

> Our WSS4J In/Out interceptors[1][2] do not appear to be requiring UsernameTokens to have
timestamps and nonces.  From [3], lines 176-190, these are used to prevent replay attacks
(i.e., an intruder just copying the entire soap header, encrypted or not, and reusing it for
another request).  
> To fix this problem, this blog sample[4] created a separate interceptor that will reject
any UsernameToken that does not have both a timestamp and a nonce.  Perhaps we should update
our WSS4J in/out interceptors to require both of these, so external users don't need to do
this.
> A question though--I'm unsure where the nonce-checking is being done--our WSS4J interceptors
seem to be ignoring them, but perhaps WSS4J is doing the checking/validation that they are
not being used more then once.
