Descriptions

iPerf3 before 3.17, when used with OpenSSL before 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 attacker to recover credential plaintext. It requires the attacker to send a large number of messages for decryption, as described in "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.

iPerf3 anterior a 3.17, cuando se usa con OpenSSL anterior a 3.2.0 como servidor con autenticación RSA, permite un canal lateral de temporización en las operaciones de descifrado RSA. Este canal lateral podría ser suficiente para que un atacante recupere el texto sin formato de las credenciales. Requiere que el atacante envíe una gran cantidad de mensajes para descifrarlos, como se describe en "Everlasting ROBOT: the Marvin Attack" de Hubert Kario.

A timing-based side-channel flaw was found in iperf3. If the iperf3 server is running with the --rsa-private-key-path option, the user authentication API can be attacked.
