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 45.
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.

Mass assignment is a feature of Rails which allows an application to create a record from the values of a hash.
Example:
User.new(params[:user])
Unfortunately, if there is a user field called admin
which controls administrator access, now any user can make themselves an administrator.
attr_accessible
and attr_protected
can be used to limit mass assignment. However, Brakeman will warn unless attr_accessible
is used, or mass assignment is completely disabled.
There are two different mass assignment warnings which can arise. The first is when mass assignment actually occurs, such as the example above. This results in a warning like
Unprotected mass assignment near line 61: User.new(params[:user])
The other warning is raised whenever a model is found which does not use attr_accessible
. This produces generic warnings like
Mass assignment is not restricted using attr_accessible
with a list of affected models.
In Rails 3.1 and newer, mass assignment can easily be disabled:
config.active_record.whitelist_attributes = true
Unfortunately, it can also easily be bypassed:
User.new(params[:user], :without_protection => true)
Brakeman will warn on uses of without_protection
.

Brakeman reports on several cases of remote code execution, in which a user is able to control and execute code in ways unintended by application authors.
The obvious form of this is the use of eval
with user input.
However, Brakeman also reports on dangerous uses of send
, constantize
, and other methods which allow creation of arbitrary objects or calling of arbitrary methods.

Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"
