CWE-294
Authentication Bypass by Capture-replay
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).
Impactr finds and proves whether CWE-294 — or flaws like it — are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
