Can a web application be vulnerable to command injection attack?
Ideally, you are supposed to lookup DNS and resolve hostnames to IP addresses using this web application. However, the code is vulnerable to ‘command injection attack’. As you know, in bash we can execute two commands one after the other by typing:
Which is an example of a command injection vulnerability?
Example of a Command Injection Vulnerability. In this example of the command injection vulnerability we are using the ping functionality which is notoriously insecure on many routers. Imagine a vulnerable application that has a common function that passes an IP address from a user input to the system’s ping command.
How is Bash vulnerable to command injection attack?
However, the code is vulnerable to ‘command injection attack’.
