This section briefly describes the enhancements in Lasernet 10.8.1.

“Strict Kex Extension” Support

Lasernet now supports an OpenSSH extension that strengthens SFTP protocol security.

NIST CVE-2023-48795 describes an SSH/OpenSSH vulnerability that enables remote attackers to bypass integrity checks by omitting packets from connection negotiation messages. This prefix truncation attack can result in downgraded security and is known as a Terrapin attack. This is a vulnerability of SSH/SFTP servers; Lasernet is an SFTP client and does not contain a vulnerability.

The OpenSSH “strict kex extension” prevents Terrapin attacks. Because Lasernet acts as an SFTP client, it must support the OpenSSH strict kex extension in order to connect to SFTP servers that are using that extension. If an SFTP server does have a “Require strict kex extension” mode (or similar) enabled, Lasernet can now connect to the SFTP server and communicate with it in accordance with the requirements of that mode.
