Descriptions

When serving resources from a network location using the NTFS file system, Apache Tomcat versions 10.0.0-M1 to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances.

Cuando se sirven recursos desde una ubicación de red usando el sistema de archivos NTFS, Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M9, versiones 9.0.0.M1 hasta 9.0.39, versiones 8.5.0 hasta 8.5.59 y versiones 7.0.0 hasta 7.0.106, fueron susceptibles a una divulgación del código fuente JSP en algunas configuraciones. La causa raíz fue el comportamiento inesperado de la función File.getCanonicalPath() de la API JRE que a su vez fue causado por el comportamiento incoherente de la API de Windows (FindFirstFileW) en algunas circunstancias

A flaw was found in Apache Tomcat. When serving resources from a network location using the NTFS file system, it was possible to bypass security constraints and view the source code for JSPs in some configurations. The root cause was the unexpected behavior of the JRE API File.getCanonicalPath(), which was caused by the inconsistent behavior of the Windows API (FindFirstFileW) in some circumstances. The highest threat from this vulnerability is to confidentiality.
