Vulnerability Details : CVE-2013-0156

active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.

- Metasploit Modules Related To CVE-2013-0156

Ruby on Rails XML Processor YAML Deserialization Scanner
This module attempts to identify Ruby on Rails instances vulnerable to an arbitrary object instantiation flaw in the XML request processor.
Ruby on Rails XML Processor YAML Deserialization Code Execution
This module exploits a remote code execution vulnerability in the XML request processor of the Ruby on Rails application framework. This vulnerability allows an attacker to instantiate a remote object, which in turn can be used to execute any ruby code remotely in the context of the application. This module has been tested across multiple versions of RoR 3.x and RoR 2.x The technique used by this module requires the target to be running a fairly recent version of Ruby 1.9 (since 2011 or so). Applications using Ruby 1.8 may still be exploitable using the init_with() method, but this has not been demonstrated.
