Synopsis
Multiple vulnerabilities have been discovered in Rails, the worst of which
leading to the execution of arbitrary SQL statements.
2.
Impact Information
Background
Ruby on Rails is a web-application and persistence framework.
Description
The following vulnerabilities were discovered:
- sameer
reported that lib/action_controller/cgi_process.rb removes the
:cookie_only attribute from the default session options
(CVE-2007-6077), due to an incomplete fix for CVE-2007-5380 (GLSA
200711-17).
- Tobias Schlottke reported that the :limit and
:offset parameters of ActiveRecord::Base.find() are not properly
sanitized before being processed (CVE-2008-4094).
- Steve from
Coderrr reported that the CRSF protection in protect_from_forgery()
does not parse the text/plain MIME format (CVE-2008-7248).
- Nate reported a documentation error that leads to the assumption
that a block returning nil passed to
authenticate_or_request_with_http_digest() would deny access to the
requested resource (CVE-2009-2422).
- Brian Mastenbrook reported
an input sanitation flaw, related to multibyte characters
(CVE-2009-3009).
- Gabe da Silveira reported an input sanitation
flaw in the strip_tags() function (CVE-2009-4214).
- Coda Hale
reported an information disclosure vulnerability related to HMAC
digests (CVE-2009-3086).
Impact
A remote attacker could send specially crafted requests to a vulnerable
application, possibly leading to the execution of arbitrary SQL
statements or a circumvention of access control. A remote attacker
could also conduct session fixation attacks to hijack a user's session
or bypass the CSRF protection mechanism, or furthermore conduct
Cross-Site Scripting attacks or forge a digest via multiple attempts.

Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All Ruby on Rails 2.3.x users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-2.3.5"
|
All Ruby on Rails 2.2.x users should upgrade to the latest version:
Code Listing 3.2: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose "=dev-ruby/rails-2.2.3-r1"
|
NOTE: All applications using Ruby on Rails should also be configured to
use the latest version available by running "rake rails:update" inside
the application directory.
