Understanding the Ramifications of Server-Side Request Forgery (SSRF)

Server Side Request Forgery


Types Of Server Vulnerabilities

So what methods do hackers use when attempting SSRF attacks? What features make a business more vulnerable to these attacks than others? And what can you do to reinforce these weak points so your business doesn't become a victim?

Remember that any web application that has user-controllable data is vulnerable to these attacks. These features are just a few examples of such weak points in a web application.

File Processing

File processing refers to web applications that organize and store files. These include scripts, import-export formats, and even configuration files. 

This helps users find and retrieve and information that they need from your business on a normal day. They might even use this to store their own information for later use. There are many different kinds of file processing systems that businesses use mainly because they are convenient both for the business and for their users.

The only drawback is that these systems are extremely easy to exploit. It's based on user-controllable data that you don't necessarily want available to just anyone. For this reason, hackers tend to target these systems for many different kinds of attacks.


Webhooks are a method of connecting an external plugin to a web application. The webhook uses a triggering event to activate the external plugin. For example, signing up for a service might trigger said service sending a welcome email. 

This creates automation that's standardized and convenient to use. But if the plugin isn't secured the way that it should be, then it creates a weak point for hackers to exploit. 

By opening up that user-controllable data to just anyone, a hacker can now use that to take control of an HTTP server all too easily. This leaves your business vulnerable to an SSRF attack.


SSRF Example

A good example of an SSRF attack is the attack on banking company CapitalOne. This event happened in 2019 and lead to over 100,000 client records being disclosed. It's now one of the most well-known SSRF attacks.

CapitalOne uses Amazon Web Services or AWS. The hacker was able to acquire credentials by using the company's server. Because AWS allows the application to have its own metadata, the hacker was able to use that as a springboard to access those credentials. 

These credentials allowed them to obtain CapitalOne's entire database. This gave them access to all of the customers in the database. If CapitalOne had been more vigilant, then this might have been prevented.

Prevent Server-Side Request Forgery

If you want to help your business with avoiding server-side request forgery, then there are a few things that you can do. These all help to fortify your servers. This will help you defend your business against all kinds of server attacks.

These are just some of the ways that you can protect your business and assets.


Firewalls have been in use for over two decades now. Rather than searching for weak points in your security like a vulnerability scanner will, these devices will protect your server from active threats. It scans all network traffic going in and out of the server to accomplish this.

Once the traffic is scanned, the firewall then decides which commands can go in and out of the server. This prevents many different kinds of attacks since it can recognize unauthorized or malicious commands. This includes SSRF attacks that your business might fall victim to.

It's one of the most basic ways to protect your business.

Wifi Pen Testing

Wifi pen testing is another kind of vulnerability scanner. These tests are more specific to your business's wireless network. This helps you ensure that your wifi is secure from hackers.

Any devices connected to your business's network need to be secured. If they aren't, then these can also act as weak points to taking over your business's server. 

This points out these weak points so that you can reinforce them. This way, you don't need to worry about anyone using your wireless network to access your server. It keeps you in control of your own network.

Web Scanner

A web scanner is another type of vulnerability scanner. These are going to scan your website itself for any weak points in your security. For example, it's going to look for unsecured exterior services that hackers can take advantage of.

This allows you to reinforce these weak points. You'll know which spots to look out for so you can protect your business more effectively.

It means your customers and your business will be protected from all sorts of server attacks, including SSRF attacks. You'll never have to worry about losing control over your server with these scans.
