Successfully using libcurl to do a transfer to a specific HTTP origin
(hostA) with Digest authentication and then changing the origin to a
different one (hostB) for a second transfer, reusing the same handle, makes
libcurl wrongly pass on the Authorization: header field meant for hostA,
to hostB.
Weakness
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
