Jerry Gamblin decidi\u00f3 investigar la prevalencia de un problema recientemente descubierto el problema<\/a><\/noindex> en las im\u00e1genes de Docker de la distribuci\u00f3n Alpine, relacionado con la asignaci\u00f3n de una contrase\u00f1a vac\u00eda para el usuario root. El an\u00e1lisis de mil de los contenedores m\u00e1s populares del cat\u00e1logo de Docker Hub demostr\u00f3<\/a><\/noindex>, que en 194<\/a><\/noindex> de los cuales (19.4%) para root se ha establecido una contrase\u00f1a vac\u00eda sin bloqueo de cuenta (\"root:::0:::::\" en lugar de \"root:!::0:::::\").<\/p>\n

En el caso de utilizar en el contenedor los paquetes shadow y linux-pam, utilizar la contrase\u00f1a vac\u00eda de root permite<\/a><\/noindex> aumenta sus privilegios dentro del contenedor si se tiene acceso no privilegiado al contenedor o despu\u00e9s de explotar una vulnerabilidad en un servicio no privilegiado que se ejecuta en el contenedor. Tambi\u00e9n se puede conectar al contenedor con derechos de root si se tiene acceso a la infraestructura, es decir, la posibilidad de conectarse a trav\u00e9s de un terminal a TTY, que se especifica en la lista \/etc\/securetty. A trav\u00e9s de SSH, el acceso con una contrase\u00f1a vac\u00eda est\u00e1 bloqueado.<\/p>\n

Los m\u00e1s populares entre los contenedores con contrase\u00f1a vac\u00eda de root<\/a><\/noindex> son microsoft\/azure-cli<\/a><\/noindex>, kylemanna\/openvpn<\/a><\/noindex>, governmentpaas\/s3-resource<\/a><\/noindex>, phpmyadmin\/phpmyadmin<\/a><\/noindex>, mesosphere\/aws-cli<\/a><\/noindex> y hashicorp\/terraform<\/a><\/noindex>, que cuentan con m\u00e1s de 10 millones de descargas. Tambi\u00e9n se destacan los contenedores
\ngovuk\/gemstash-alpine<\/a><\/noindex> (500 mil), monsantoco\/logstash<\/a><\/noindex> (5 millones),
\navhost\/docker-matrix-riot<\/a><\/noindex> (1 mill\u00f3n),
\nazuresdk\/azure-cli-python<\/a><\/noindex> (5 millones)
\ny ciscocloud\/haproxy-consul<\/a><\/noindex> (1 mill\u00f3n). Casi todos estos contenedores est\u00e1n basados en Alpine y no utilizan los paquetes shadow y linux-pam. La excepci\u00f3n es solo microsoft\/azure-cli, que se basa en Debian.<\/p>\n
