CVE-2023-43809

Summary

CVE-2023-43809 is a vulnerability affecting Soft Serve, a self-hostable Git server. Prior to version 0.6.2, this issue allows unauthenticated, remote attackers to bypass public key authentication when keyboard-interactive SSH authentication is active. The flaw lies in the insufficient validation procedures during the SSH request handshake, enabling an attacker to present manipulated SSH requests using the keyboard-interactive authentication mode. This could potentially result in unauthorized access to the Soft Serve. To mitigate this risk, Soft Serve users are advised to upgrade to the latest version, v0.6.2, as soon as possible. As a temporary measure, users can disable Keyboard-Interactive SSH Authentication.
