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.

A local privilege escalation vulnerability was discovered in Erlang/OTP prior to version 23.2.3. By adding files to an existing installation's directory, a local attacker could hijack accounts of other users running Erlang programs or possibly coerce a service running with "erlsrv.exe" to execute arbitrary code as Local System. This can occur only under specific conditions on Windows with unsafe filesystem permissions. Se detectó una vulnerabilidad de escalada de privilegios local en Erlang/OTP anterior a versión 23.2.3. Al agregar archivos a un directorio de instalación existente, un atacante local podría secuestrar cuentas de otros usuarios que ejecutan programas Erlang o posiblemente coaccionar un servicio que se ejecuta con "erlsrv.exe" para ejecutar código arbitrario como Local System. • https://deepsurface.com/deepsurface-security-advisory-local-privilege-escalation-in-erlang-on-windows-cve-2021-29221 https://github.com/erlang/otp/releases/tag/OTP-23.2.3 • CWE-426: Untrusted Search Path •
