command-injection-testing

To test for OS command injection, inject shell metacharacters and commands into user-controlled inputs to check if arbitrary operating system commands execute on the server, covering direct, blind, and argument injection vectors.

Blind command injection occurs when command output is not visible in the response. It is detected by measuring response delays using time-based techniques or monitoring external out-of-band callbacks to confirm execution.

Yes, command injection testing validates vulnerabilities across various platforms like Linux and Windows by injecting platform-specific shell metacharacters into user inputs such as filenames passed to system commands.

To validate CWE-78 argument injection, test if additional arguments can be injected into user-controlled inputs to alter the behavior of existing system commands executed by the application.

The best way to detect direct command injection is to inject shell metacharacters into user inputs and observe whether the executed command output is directly visible within the application response.

Time-based detection for command injection should be used when application responses do not return command output directly, requiring response delay measurements to confirm vulnerability execution.
