CVE-2011-2894 – Security: Chosen commands execution on the server (Framework) or authentication token bypass (Security) by objects de-serialization

https://notcve.org/view.php?id=CVE-2011-2894

Spring Framework 3.0.0 through 3.0.5, Spring Security 3.0.0 through 3.0.5 and 2.0.0 through 2.0.6, and possibly other versions deserialize objects from untrusted sources, which allows remote attackers to bypass intended security restrictions and execute untrusted code by (1) serializing a java.lang.Proxy instance and using InvocationHandler, or (2) accessing internal AOP interfaces, as demonstrated using deserialization of a DefaultListableBeanFactory instance to execute arbitrary commands via the java.lang.Runtime class. Spring Framework v3.0.0 hasta la v3.0.5, v3.0.0 hasta la de Spring Security v3.0.5 y v2.0.0 y v2.0.6, y posiblemente otras versiones permite des-serializar objetos de fuentes no fiables, lo que permite a atacantes remotos eludir las restricciones de seguridad existentes y permite la ejecución de código no seguro (1) serializando una instancia de java.lang.Proxy y mediante el uso de InvocationHandler, o (2) accediendo a las interfaces internas AOP, como se demuestra con la des-serialización de una instancia de DefaultListableBeanFactory para ejecutar código arbitrario a través de la clase java.lang.Runtime. • http://osvdb.org/75263 http://securityreason.com/securityalert/8405 http://www.redhat.com/support/errata/RHSA-2011-1334.html http://www.securityfocus.com/archive/1/519593/100/0/threaded http://www.securityfocus.com/bid/49536 http://www.springsource.com/security/cve-2011-2894 https://exchange.xforce.ibmcloud.com/vulnerabilities/69687 https://web.archive.org/web/20120307233721/http://www.springsource.com/security/cve-2011-2894 https://access.redhat.com/security/cve/CVE-2011-2894 • CWE-502: Deserialization of Untrusted Data •
