Injection is #1 on the 2013 OWASP Top Ten web security risks. SQL injection is when a user is able to manipulate a value which is used unsafely inside a SQL query. This can lead to data leaks, data loss, elevation of privilege, and other unpleasant outcomes.
Brakeman focuses on ActiveRecord methods dealing with building SQL statements.
A basic (Rails 2.x) example looks like this:
User.first(:conditions => "username = '#{params[:username]}'")Brakeman would produce a warning like this:
Possible SQL injection near line 30: User.first(:conditions => ("username = '#{params[:username]}'"))The safe way to do this query is to use a parameterized query:
User.first(:conditions => ["username = ?", params[:username]])Brakeman also understands the new Rails 3.x way of doing things (and local variables and concatenation):
username = params[:user][:name].downcase
password = params[:user][:password]
User.first.where("username = '" + username + "' AND password = '" + password + "'")This results in this kind of warning:
Possible SQL injection near line 37:
User.first.where((((("username = '" + params[:user][:name].downcase) + "' AND password = '") + params[:user][:password]) + "'"))See the Ruby Security Guide for more information and Rails-SQLi.org for many examples of SQL injection in Rails.

Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 30.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.
See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.
