CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

The SSH Plugin stores credentials which allow jobs to access remote servers via the SSH protocol. User passwords and passphrases for encrypted SSH keys are stored in plaintext in a configuration file. El plugin SSH almacena credenciales, lo que permite que las tareas accedan a servidores remotos mediante el protocolo SSH. Las contraseñas de usuarios así como las frases utilizadas como contraseñas para claves SSH cifradas se almacenan en texto plano en un archivos de configuración. • https://jenkins.io/security/advisory/2017-07-10 • CWE-522: Insufficiently Protected Credentials •
