iPerf3 prior to 3.17, when used with OpenSSL prior to 3.2.0 as a server with RSA authentication, allows a timing side channel in RSA decryption operations. This side channel could be sufficient for an malicious user to recover credential plaintext. It requires the malicious user to send a large number of messages for decryption, as described in "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.
