Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in Rails, the worst of |
| 19 |
which leading to the execution of arbitrary SQL statements. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Ruby on Rails is a web-application and persistence framework. |
| 25 |
|
| 26 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The following vulnerabilities were discovered: |
| 39 |
|
| 40 |
* sameer reported that lib/action_controller/cgi_process.rb removes |
| 41 |
the :cookie_only attribute from the default session options |
| 42 |
(CVE-2007-6077), due to an incomplete fix for CVE-2007-5380 (GLSA |
| 43 |
200711-17). |
| 44 |
|
| 45 |
* Tobias Schlottke reported that the :limit and :offset parameters of |
| 46 |
ActiveRecord::Base.find() are not properly sanitized before being |
| 47 |
processed (CVE-2008-4094). |
| 48 |
|
| 49 |
* Steve from Coderrr reported that the CRSF protection in |
| 50 |
protect_from_forgery() does not parse the text/plain MIME format |
| 51 |
(CVE-2008-7248). |
| 52 |
|
| 53 |
* Nate reported a documentation error that leads to the assumption |
| 54 |
that a block returning nil passed to |
| 55 |
authenticate_or_request_with_http_digest() would deny access to the |
| 56 |
requested resource (CVE-2009-2422). |
| 57 |
|
| 58 |

| 60 |
|
| 61 |

| 63 |
|
| 64 |
* Coda Hale reported an information disclosure vulnerability related |
| 65 |
to HMAC digests (CVE-2009-3086). |

Impact |
| 68 |
====== |
| 69 |
|
| 70 |
A remote attacker could send specially crafted requests to a vulnerable |
| 71 |
application, possibly leading to the execution of arbitrary SQL |
| 72 |
statements or a circumvention of access control. A remote attacker |
| 73 |
could also conduct session fixation attacks to hijack a user's session |
| 74 |
or bypass the CSRF protection mechanism, or furthermore conduct |
| 75 |
Cross-Site Scripting attacks or forge a digest via multiple attempts. |
| 76 |
|
| 77 |
Workaround |
| 78 |
========== |
| 79 |
|
| 80 |
There is no known workaround at this time. |
| 81 |
|
| 82 |
Resolution |
| 83 |
========== |
| 84 |
|
| 85 |
All Ruby on Rails 2.3.x users should upgrade to the latest version: |
| 86 |
|
| 87 |
# emerge --sync |
| 88 |
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-2.3.5" |
| 89 |
|
| 90 |
All Ruby on Rails 2.2.x users should upgrade to the latest version: |
| 91 |
|
| 92 |
# emerge --sync |
| 93 |
# emerge --ask --oneshot --verbose "=dev-ruby/rails-2.2.3-r1" |
| 94 |
|
| 95 |
NOTE: All applications using Ruby on Rails should also be configured to |
| 96 |
use the latest version available by running "rake rails:update" inside |
| 97 |
the application directory. |
