Web application security should never take a backseat. If we don’t closely monitor the way our applications validate user-provided data, we can leave them vulnerable to SSRF (Server-Side Request Forgery) threats, which can be used to initiate damaging cyberattacks.
When we say that our application isn’t validating user input properly, we mean that the application is blindly accessing insecure external resources based on user-supplied instructions. Threat actors can initiate SSRF attacks by supplying a URL to our web application that references a malicious resource, ultimately placing them in the driver’s seat to control subsequent requests made by the application. Successful SSRF attacks can steal extremely sensitive data related to our server configuration or other important network resources, and they’re also one of many ways attackers can launch DoS (Denial of Service) attacks.
Cloudmersive SSRF Threat Detection API
Thankfully, SSRF threats can be detected and averted by carefully analyzing user-supplied URL input. Our SSRF Threat Detection API is designed specifically to detect threatening URLs from a user input string, identifying whether the URL contents are intended to compromise our web application. The API response provides a Boolean (CleanURL = True or False) along with a string describing the threat level of that URL.
Just like any Cloudmersive API, you can find code SSRF Threat Detection code examples in a variety of common programming languages available through your account management page. You can implement a powerful anti-SSRF threat policy in minutes, authorizing requests with your universal API key.
