CVE-2011-3190

Algunas implementaciones del conector del protocolo AJP en Apache Tomcat v7.0.0 a v7.0.20, v6.0.0 a v6.0.33, v5.5.0 a v5.5.33, y posiblemente con otras versiones, permiten a atacantes remotos falsificar peticiones AJP, eludir la autenticación y obtener información sensible haciendo que el conector interprete un cuerpo de una petición como una nueva solicitud.

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.
