CVSS: 5.9EPSS: 95%CPEs: 79EXPL: 3CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
18 Dec 2023 — 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 phas... • https://packetstorm.news/files/id/176280 • CWE-222: Truncation of Security-relevant Information CWE-354: Improper Validation of Integrity Check Value •

09 Jul 2021 — PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. This makes it easier for an attacker-controlled SSH server to present a later spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for purposes that are undesired by the client user). PuTTY versiones hasta 0.75, procede con establecer una sesión SSH incluso si nunca ha enviado una respuesta de autenticación sustantiva. Esto facilita a... • https://git.tartarus.org/?p=simon/putty.git%3Ba=commit%3Bh=1dc5659aa62848f0aeb5de7bd3839fecc7debefa • CWE-345: Insufficient Verification of Data Authenticity •

21 May 2021 — PuTTY before 0.75 on Windows allows remote servers to cause a denial of service (Windows GUI hang) by telling the PuTTY window to change its title repeatedly at high speed, which results in many SetWindowTextA or SetWindowTextW calls. NOTE: the same attack methodology may affect some OS-level GUIs on Linux or other platforms for similar reasons. PuTTY versiones anteriores a 0.75, en Windows permite a servidores remotos causar una denegación de servicio (colgar la GUI de Windows) al indicar a la ventana de P... • https://docs.ssh-mitm.at/puttydos.html •

01 Oct 2019 — PuTTY before 0.73 on Windows improperly opens port-forwarding listening sockets, which allows attackers to listen on the same port to steal an incoming connection. PuTTY versiones anteriores a 0.73 en Windows abre inapropiadamente los sockets de escucha de reenvío de puertos, lo que permite a los atacantes escuchar sobre el mismo puerto para robar una conexión entrante. • https://lists.tartarus.org/pipermail/putty-announce/2019/000029.html • CWE-770: Allocation of Resources Without Limits or Throttling •
