FileZilla < 3.67.0 Insecure Key Recovery Vulnerability (CVE-2024-31497)

medium Nessus Plugin ID 206646

Language:

Synopsis

The remote host is affected by a key recovery vulnerability.

Description

The FileZilla application installed on the remote host is prior to 3.67.0. It is, therefore, affected by a key recovery vulnerability where biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to FileZilla Client version 3.67.0 or later.
