To avoid API security risks and API threats, you need to know the OWASP top 10 API vulnerabilities. In this blog, we break down OWASP API security risks and how to prevent them.
Open Web Application Security Project (OWASP) compiles a list of API security risks every year. By preventing the top OWASP API security risks, you can protect your business. Understanding and mitigating these security risks is especially critical in the enterprise.
The exponential growth of API usage in today’s digital world brings the risk of those APIs being vulnerable to attacks. Cyberattacks have become commonplace in today’s news, with multinational corporations making headlines for the wrong reasons due to a lack of API protection.
These data breaches can bring fines, litigation, and — possibly worst of all — damage to your reputation. It only takes one data leak for your brand to suffer irreparable damage.
To protect against threats and attacks, you need:
The OWASP Top 10 vulnerabilities, is a list produced by security experts around the globe to highlight the web application and API security risks that are deemed the most critical. Some vulnerabilities can be solved with SAST. Others can be solved with API management.
The OWASP Top 10 API list is as follows. Read along or jump to the vulnerability you want to explore:
1. Broken Object Level API Authorization
Broken object level authorization is characteristic of APIs exposes endpoints that handle object identifiers. This creates a wide attack surface Level Access Control issue.
So, how can you prevent this OWASP API security risk?

When authentication mechanisms are implemented incorrectly, attackers can compromise authentication tokens or exploit implementation flaws to assume the identity of another user. This compromises the security to that particular user, as well as the overall API security.
Developers may expose all their object properties without taking into consideration these properties’ individual sensitivities. Instead, they rely on the clients for data filtering before displaying it to the user.
If an API does not impose a restriction on the size or number of resources that a user/client can request, server performance can suffer. And it lead to a Denial of Service (DoS). This also creates an opportunity for authentication flaws such as brute force.

Authorization flaws can arise from complex access control polices, different hierarchies/groups/roles, and a blurred distinction between administrative and regular functions. These issues allow attackers to gain access to other users’ resources and/or administrative functions.
When client-provided data (JSON, for example) is bound to data models without applying proper filtering properties, attackers are able to modify object properties they are not supposed to. This can be done by exploring API endpoints, guessing object properties, reading documentation, or using request payloads to provide additional object properties.
Misconfiguration can result from a number of common issues, including:
Injection flaws occur when a command or query causes untrusted data to be sent to an interpreter. Malicious data from an attacker can trick an interpreter into accessing data without proper authorization or executing unintended commands.

Composing proper and updated documentation is critically important for APIs as they tend to expose more endpoints than traditional web applications. An inventory of deployed API versions and proper hosts can help mitigate common IT security risks like deprecated API versions and exposed debug endpoints.
This is perhaps the most exploited security vulnerability. Hackers rely on a lack of logging and monitoring to compromise data unnoticed. By the time the breach is detected, it is often too late.
The best way to prevent OWASP API security vulnerabilities is to use an API management platform like Akana.
