API Injections. What is it?

Thread π§΅π
API injection occurs when the user sends malicious code with the API request as part of the request body or query parameter.
Most of the time, the code is a database query that executes and corrupts the database.

π Command Injections
When an API injection brings a system command to the server, it turns into a Command injection.
The command, if executed, can delete site directories or the entire site from the server.

π Example
A simple example is when you want to view the uploaded file. The API will take the file id to the server to retrieve it. If the user sends a malicious code along with the file id, it will be executed on the server.

π API Injection impact
API injection can affect your API in the following ways:
- Database leak
- Authentication issues
- Full take-over of the system
- Denial of service (DoS)
- Attackers may carry out remote code execution
- Attackers may also create new functionality

π Prevention techniques
- The user input should be sanitized properly both on the client and server sides.
- We can encode special characters and change their meaning. This way interpreter will treat them as data rather than special characters.
