CVE-2019-0232 – Apache Tomcat - CGIServlet enableCmdLineArguments Remote Code Execution
https://notcve.org/view.php?id=CVE-2019-0232
When running on Windows with enableCmdLineArguments enabled, the CGI Servlet in Apache Tomcat 9.0.0.M1 to 9.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 is vulnerable to Remote Code Execution due to a bug in the way the JRE passes command line arguments to Windows. The CGI Servlet is disabled by default. The CGI option enableCmdLineArguments is disable by default in Tomcat 9.0.x (and will be disabled by default in all versions in response to this vulnerability). For a detailed explanation of the JRE behaviour, see Markus Wulftange's blog (https://codewhitesec.blogspot.com/2016/02/java-and-command-line-injections-in-windows.html) and this archived MSDN blog (https://web.archive.org/web/20161228144344/https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/). 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. • https://www.exploit-db.com/exploits/47073 https://github.com/pyn3rd/CVE-2019-0232 https://github.com/jas502n/CVE-2019-0232 https://github.com/jaiguptanick/CVE-2019-0232 https://github.com/setrus/CVE-2019-0232 https://github.com/cyy95/CVE-2019-0232-EXP https://github.com/xsxtw/CVE-2019-0232 https://github.com/Nicoslo/Windows-exploitation-Apache-Tomcat-8.5.19-CVE-2019-0232- https://github.com/Nicoslo/Windows-Exploitation-Web-Server-Tomcat-8.5.39-CVE-2019-0232 http:& • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2019-0199 – tomcat: Apache Tomcat HTTP/2 DoS
https://notcve.org/view.php?id=CVE-2019-0199
The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS. La implementación HTTP/2 en Apache Tomcat desde 9.0.0.M1 hasta 9.0.14 y desde 8.5.0 hasta 8.5.37 aceptaba flujos con números excesivos de tramas SETTINS y permitía a los clientes mantener flujos abiertos sin datos de lectura/escritura o solicitud/respuesta. Manteniendo flujos abiertos para peticiones que utilizaban bloqueo I/O en el Servlet API´s, los clientes eran capaces de hacer que los hilos (threads) del lado del servidor se bloquearan, provocando el agotamiento de los hilos y la denegación del servicio (DoS). A flaw was found in Apache Tomcat, where the HTTP/2 implementation accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open, which enables them to cause server-side threads to block. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00090.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00054.html http://www.securityfocus.com/bid/107674 https://access.redhat.com/errata/RHSA-2019:3929 https://access.redhat.com/errata/RHSA-2019:3931 https://lists.apache.org/thread.html/158ab719cf60448ddbb074798f09152fdb572fc8f781e70a56118d1a%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thre • CWE-400: Uncontrolled Resource Consumption •
