GitHub ha revelado informaci\u00f3n sobre una vulnerabilidad que permite acceder al contenido de las variables de entorno expuestas en los contenedores utilizados en la infraestructura de trabajo. La vulnerabilidad fue descubierta por un participante del programa Bug Bounty, que pretende recibir una recompensa por encontrar problemas de seguridad. El problema afecta tanto al servicio GitHub.com como a las configuraciones de GitHub Enterprise Server (GHES) que se ejecutan en los sistemas de los usuarios. <\/p>\n
El an\u00e1lisis de registros y la auditor\u00eda de la infraestructura no detectaron signos de explotaci\u00f3n de la vulnerabilidad en el pasado, excepto por la actividad del investigador que inform\u00f3 sobre el problema. Sin embargo, se ha iniciado el reemplazo de todas las claves de cifrado y credenciales que podr\u00edan haber estado potencialmente comprometidas en caso de que un atacante hubiera explotado la vulnerabilidad. El reemplazo de las claves internas caus\u00f3 la interrupci\u00f3n de algunos servicios del 27 al 29 de diciembre. Los administradores de GitHub intentaron considerar los errores cometidos durante la actualizaci\u00f3n de claves realizada ayer, que afecta a los clientes. <\/p>\n
Entre otras cosas, se actualiz\u00f3 la clave GPG utilizada para firmar digitalmente los commits hechos a trav\u00e9s del editor web de GitHub al aceptar pull requests en el sitio o a trav\u00e9s de la herramienta Codespace. La clave antigua dej\u00f3 de ser v\u00e1lida el 16 de enero a las 23:00 hora de Mosc\u00fa, y a partir de ayer se est\u00e1 utilizando una nueva clave. A partir del 23 de enero, todos los nuevos commits firmados con la clave anterior no ser\u00e1n marcados en el sitio de GitHub como verificados. <\/p>\n
El 16 de enero tambi\u00e9n se actualizaron las claves p\u00fablicas utilizadas para cifrar los datos del usuario enviados a trav\u00e9s de la API en GitHub Actions, GitHub Codespaces y Dependabot. Se recomienda a los usuarios que utilizan claves p\u00fablicas de GitHub para la verificaci\u00f3n local de commits y el cifrado de datos transmitidos que se aseguren de haber actualizado las claves GPG de GitHub y que sus sistemas contin\u00faen funcionando despu\u00e9s de la actualizaci\u00f3n de las claves. <\/p>\n
GitHub ya ha solucionado la vulnerabilidad en el sitio GitHub.com y ha lanzado una actualizaci\u00f3n del producto GHES 3.8.13, 3.9.8, 3.10.5 y 3.11.3, en la que se se\u00f1ala la correcci\u00f3n de CVE-2024-0200 (uso inseguro de reflejos que lleva a la ejecuci\u00f3n de c\u00f3digo o m\u00e9todos controlados por el usuario en el lado). servidores<\/a>Un ataque a las instalaciones locales de GHES podr\u00eda haber sido llevado a cabo si el atacante ten\u00eda una cuenta con derechos de gesti\u00f3n de la organizaci\u00f3n (due\u00f1o de la organizaci\u00f3n).
