CVE-2025-32433

Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. This issue is patched in versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary workaround involves disabling the SSH server or to prevent access via firewall rules.

Erlang/OTP es un conjunto de librerías para el lenguaje de programación Erlang. En versiones anteriores a OTP-27.3.3, OTP-26.2.5.11 y OTP-25.3.2.20, un servidor SSH podía permitir a un atacante realizar una ejecución remota de código (RCE) sin autenticación. Al explotar una falla en la gestión de mensajes del protocolo SSH, un atacante podría obtener acceso no autorizado a los sistemas afectados y ejecutar comandos arbitrarios sin credenciales válidas. Este problema está corregido en las versiones OTP-27.3.3, OTP-26.2.5.11 y OTP-25.3.2.20. Una solución temporal consiste en deshabilitar el servidor SSH o impedir el acceso mediante reglas de firewall.
