Detailsinfo

A vulnerability has been found in esnet iPerf3 up to 3.16 and classified as problematic. Affected by this vulnerability is an unknown code block of the component OpenSSL Handler. The manipulation with an unknown input leads to a cryptographic issue vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The weakness was disclosed by Hubert Kario. It is possible to read the advisory at github.com. This vulnerability is known as CVE-2024-26306 since 02/16/2024.
