En el paquete Net-SNMP, que implementa los protocolos SNMP v1, SNMP v2c y SNMP v3, se ha encontrado una vulnerabilidad (CVE-2025-68615) que permite la ejecuci\u00f3n remota de c\u00f3digo en un servidor que utiliza el servicio snmptrapd para recibir y procesar mensajes trap de los dispositivos. Por defecto, el servicio acepta solicitudes en el puerto UDP 162 y se ejecuta con privilegios de root. Se ha asignado un nivel cr\u00edtico de peligro a este problema (9.8 de 10). El ataque puede llevarse a cabo sin autenticaci\u00f3n. <\/p>\n

La vulnerabilidad se debe a una verificaci\u00f3n incorrecta del tama\u00f1o de OID (\"trapOidLen >= 0\" en lugar de \"trapOidLen > 0\") antes de copiar los datos especificados en el paquete en un b\u00fafer de tama\u00f1o fijo. La transmisi\u00f3n de paquetes especialmente dise\u00f1ados provoca la escritura de datos fuera del b\u00fafer trapOid, lo que puede ser explotado para ejecutar c\u00f3digo del atacante con los privilegios del proceso snmptrapd. La vulnerabilidad se ha corregido en las actualizaciones Net-SNMP 5.9.5 y 5.10.pre2. Como medida de protecci\u00f3n adicional, se recomienda bloquear el acceso desde redes externas al puerto UDP 162 en el cortafuegos.
