Insecure Ruby-on-Rails Default


Ruby programmers may build websites using the popular Rails framework. It is known for having “convention over configuration,” which means that it makes certain assumptions about how a developer wants to structure their application to simplify the development process. However, these defaults are not always secure, and developers must customize them to ensure the security of their applications.

For example, by default, Rails will automatically create an HTTP session for each new user of an application. This session is stored on the server, and a cookie containing a session ID is sent to the user’s browser. After that, the user’s identity is verified for upcoming requests using the session ID. However, this can be a security risk, as session IDs can be stolen or guessed, allowing attackers to gain unauthorized access to the application.

Additionally, Rails applications often use SQL databases to store data. By default, Rails will generate SQL queries based on user input, which can be susceptible to SQL injection attacks. This is an attack where an attacker can insert malicious code into an SQL query, allowing them to access or manipulate data in the database.

To prevent these attacks, hire ruby on rails developers that must carefully configure the default settings in Rails and adequately validate and sanitize user input. They should also implement secure authentication and authorization mechanisms, such as using secure tokens instead of cookies for storing session information. It is also important to regularly update Rails and the underlying Ruby runtime to ensure that any security vulnerabilities are patched.

Let’s see some of the Ruby on Rails issues and that are addressed & resolved by the rails team.

Let’s Begin!

CSRF via Leaky #match Routes

Cross-Site Request Forgery (CSRF) is a type of attack that involves tricking a user into making unintended requests on a website they are currently logged in to. Leaked routes are just one of many potential ways for this to occur. A leaked path is a URL that is not intended to be publicly accessible but is accidentally exposed to the internet.

Numerous factors, such as a server not configured correctly or a code error, can cause this. If a leaked route is found, an attacker can use it to make requests on behalf of the user, potentially allowing them to perform actions on the site without the user’s knowledge.

To prevent CSRF attacks through leaked routes, it’s essential to secure your website correctly. This includes keeping all routes private and only allowing access to them through appropriate channels. Additionally, it’s vital to use CSRF protection mechanisms, such as random tokens, to prevent attackers from being able to make requests on behalf of the user.

Using Regular Expression in Format Validation In Ruby

In regular expressions, anchors are special characters that match the position of the string rather than reaching a specific surface. They are used to ensure that the regular expression matches the entire string or to match the start or end of the string.

There are two main anchors in regular expressions: the caret (^) and the dollar sign ($). The caret matches the start of the string, while the dollar sign matches the end. So, for example, the regular expression “^Hello” would check the string “Hello world,” but it would not match the string “world Hello.”

In format validations, regular expression anchors can be used to ensure that a given string matches a specific format. For example, a regular expression could be used to validate that a string is a valid email address by using the caret and dollar sign anchors to match the start and end of the string, along with other special characters to match the specific format of an email address. Overall, regular expression anchors are a powerful tool for ensuring that strings match a particular design in regular expressions.


In a clickjacking cyberattack, a user is deceived into clicking on the appropriate URL on a site that accomplishes something different from what the user anticipates. This can happen by placing the button or link on top of another element on the page, such as a legitimate button or link so that when the user clicks on it, they click on the hidden element.

Clickjacking can perform various malicious actions, such as stealing the user’s login information or personal data or redirecting them to a malicious website. It can also trick the user into performing unintended actions, such as liking a page or posting a comment on a social media site.

To protect against clickjacking, it’s essential to use appropriate security measures, such as implementing frame-busting code on your website to prevent your content from being embedded in other sites. It’s also vital for users to be cautious when clicking on buttons and links on unfamiliar websites and to be aware of potential signs of a clickjacking attack, such as buttons or links that do not behave as expected. You can hire dedicated developers who can assist you in navigating the process of mitigating the clickjacking attack.

User Readable Sessions OF Ruby

Signed but not encrypted cookies are used by default in Rails 3 session storage. While this guards against manipulation, it is simple for an intruder to decipher the information in a session cookie:

session_cookie = <<-STR.strip.gsub(/\n/, ”)





# => {

#   “session_id”  => “90a8f…”,

#   “_csrf_token” => “iUoXA…”,

#   “secret”      => “sekrit”

# }

You can store any private data in the session without risk. Though hopefully not a surprise, a user session could be at risk even if no sensitive data exists. An attacker who decodes the session data can learn important details about the program’s internal workings that they can utilize to their advantage. User-readable sessions go against the idea of least privilege because, although the session data must be provided to the visitor’s browser and the visitor must be able to retrieve the data, the visitor is not required to have access to the data. The default session storage was updated by Rails to be encrypted. Without the decryption key, users cannot decrypt the session content, which is unavailable on the client side.


In conclusion, Rails has some insecure defaults that can leave applications vulnerable to attack if not configured correctly. Therefore, developers need to do their due diligence and research the best security practices for their applications and ensure that their applications’ security settings are correctly configured. While Rails does provide some security features out of the box, it is still essential to take the necessary steps to ensure the security of an application.
