Esto puede afectar a aquellos que utilizan `gradlew` en sistemas tipo Unix o utilizan los scripts generados por Gradle en su aplicaci\u00f3n en sistemas tipo Unix. Para que esta vulnerabilidad sea explotable, un atacante debe ser capaz de establecer el valor de determinadas variables de entorno y hacer que esas variables de entorno sean vistas por los scripts vulnerables. Este problema ha sido parcheado en Gradle 7.2 eliminando el uso de `eval` y requiriendo el uso del shell `bash`. Hay algunas soluciones disponibles. Para los sistemas CI/CD que utilizan la herramienta de construcci\u00f3n Gradle, se puede asegurar que los usuarios no confiables no puedan cambiar las variables de entorno para el usuario que ejecuta `gradlew`. Si no se puede actualizar a Gradle 7.2, se puede generar un nuevo script `gradlew` con Gradle 7.2 y utilizarlo para versiones anteriores de Gradle. En las aplicaciones que utilizan scripts de inicio generados por Gradle, se puede asegurar que los usuarios no confiables no puedan cambiar las variables de entorno del usuario que ejecuta el script de inicio. Un script de inicio vulnerable podr\u00eda ser parcheado manualmente para eliminar el uso de `eval` o el uso de variables de entorno que afectan a la l\u00ednea de comandos de la aplicaci\u00f3n.
