CVE-2015-3253

Vulnerabilidad en la clase MethodClosure en runtime/MethodClosure.java en Apache Groovy desde la versión 1.7.0 hasta la versión 2.4.3, permite a atacantes remotos ejecutar código arbitrario y causar una denegación de servicio a través de un objeto serializado manipulado.

A flaw was discovered in the way applications using Groovy used the standard Java serialization mechanism. A remote attacker could use a specially crafted serialized object that would execute code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects are subject to this vulnerability.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache Groovy. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the Closure implementation which accepts and deserializes a Java serialized binary stream. An attacker can leverage this vulnerability to execute arbitrary code under the context of the user.

Red Hat JBoss Fuse Service Works is the next-generation ESB and business process automation infrastructure. This release of Red Hat JBoss Fuse Service Works 6.2.1 serves as a replacement for Red Hat JBoss Fuse Service Works 6.0.0. It includes various bug fixes, which are listed in the README file included with the patch files. The following security issues are fixed with this release: A flaw was discovered that when an application uses Groovy and uses the standard Java serialization mechanism, an attacker can bake a special serialized object that executes code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects are subject to this vulnerability.
