CVE-2019-0232

Cuando se ejecuta Windows con enableCmdLineArguments activado, el Servlet CGI en Apache Tomcat 9.0.0.0.M1 a 9.0.17, 8.5.0 a 8.5.39 y 7.0.0.0 a 7.0.93 es vulnerable a una Ejecución Remota de Código debido a un error en la forma en que el JRE pasa los argumentos de la línea de comando a Windows. El Servlet CGI está deshabilitado por defecto. La opción CGI enableCmdLineArguments está desactivada por defecto en Tomcat 9.0.x (y será desactivada por defecto en todas las versiones en respuesta a esta vulnerabilidad). Para una explicación detallada del comportamiento de JRE, consulte el blog de Markus Wulftange (https://codewhitesec.blogspot.com/2016/02/java-and-command-line-injections-in-windows.html) y este blog de MSDN archivado (https://web.archive.org/web/20161228144344/https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/).

A flaw was discovered in Apache Tomcat, where a Java Runtime Environment can pass a command-line argument in the Windows operating system. The execution of arbitrary commands via Tomcat’s Common Gateway Interface (CGI) Servlet, allows an attacker to perform remote code execution.
