170aaef589710c91521601000cb3b478c0e13d9f21b9c95db63d18f83815c46dThis Metasploit module attempts to identify Ruby on Rails instances vulnerable to an arbitrary object instantiation flaw in the XML request processor.
f0ae12d1945cad391cd044fe41f2338c6b4c2ee245f8e083731f15e17c72fce3The Devise authentication gem for Ruby on Rails is vulnerable to a password reset exploit leveraging type confusion. By submitting XML to rails, we can influence the type used for the reset_password_token parameter. This allows for resetting passwords of arbitrary accounts, knowing only the associated email address. This Metasploit module defaults to the most common devise URIs and response values, but these may require adjustment for implementations which customize them. Affects Devise < v2.2.3, 2.1.3, 2.0.5 and 1.5.4 when backed by any database except PostgreSQL or SQLite3. Tested with v2.2.2, 2.1.2, and 2.0.4 on Rails 3.2.11. Patch applied to Rails 3.2.12 and 3.1.11 should prevent exploitation of this vulnerability, by quoting numeric values when comparing them with non numeric values.
ccbf068c497671105a04589b9eac7aa7ba53ed1d4e9b7c9f9b06c5cde4e46e70This Metasploit module exploits a remote code execution vulnerability in the JSON 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 vulnerability is very similar to CVE-2013-0156. This Metasploit module has been tested successfully on RoR 3.0.9, 3.0.19, and 2.3.15. 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.
