Descriptions

An issue was discovered in Cloud Foundry Foundation cf-release v255 and Staticfile buildpack versions v1.4.0 - v1.4.3. A regression introduced in the Static file build pack causes the Staticfile.auth configuration to be ignored when the Static file file is not present in the application root. Applications containing a Staticfile.auth file but not a Static file had their basic auth turned off when an operator upgraded the Static file build pack in the foundation to one of the vulnerable versions. Note that Static file applications without a Static file are technically misconfigured, and will not successfully detect unless the Static file build pack is explicitly specified.

Se detectó un problema en cf-release versión v255 y Staticfile buildpack versiones v1.4.0 hasta v1.4.3 de Cloud Foundry Foundation. Una regresión introducida en el paquete de compilación de archivos Static hace que la configuración de Staticfile.auth sea ignorada cuando el archivo Static file no esté presente en la aplicación root. Las aplicaciones que contienen un archivo Staticfile.auth pero no un archivo Static tuvieron su identificación básica desactivada cuando un operador actualizó el paquete de compilación de archivos Static en la fundación de una de las versiones vulnerables. Tomar en cuenta que las aplicaciones de archivos Static sin un archivo Static están mal configuradas técnicamente y no se detectarán con éxito a menos que el paquete de compilación de archivos Static sea especificada explícitamente.
