Authentication Bypass by Capture-replay vulnerability in Mitsubishi Electric Corporation MELSEC WS Series WS0-GETH00200 all serial numbers allows a remote unauthenticated attacker to bypass authentication by capture-replay attack and illegally login to the affected module. As a result, the remote attacker who has logged in illegally may be able to disclose or tamper with the programs and parameters in the modules.
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).
