CVE-2011-2204

Apache Tomcat v5.5.x antes de v5.5.34, v6.0.33 antes de v6.x, v7.x antes de v7.0.17, cuando el MemoryUserDatabase se utiliza, crea entradas del registro que contienen las contraseñas al encontrar errores en la creación de usuarios JMX, lo que permite a usuarios locales obtener información sensible mediante la lectura de un archivo de registro.

Multiple vulnerabilities has been discovered and corrected in tomcat 5.5.x. The implementation of HTTP DIGEST authentication in tomcat was discovered to have several weaknesses. Apache Tomcat, when the MemoryUserDatabase is used, creates log entries containing passwords upon encountering errors in JMX user creation, which allows local users to obtain sensitive information by reading a log file. Apache Tomcat, when sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service by leveraging an untrusted web application. Certain AJP protocol connector implementations in Apache Tomcat allow remote attackers to spoof AJP requests, bypass authentication, and obtain sensitive information by causing the connector to interpret a request body as a new request. The updated packages have been patched to correct these issues.
