How to Inject Code into a Website for Remote Control

Introduction

Today, we will learn how to inject code into a website to gain remote control of the entire site. By identifying the programming language used on a website, we can send our own malicious code and take control. Additionally, we will explore a specific tool that simplifies the process of remote control. It's important to stay vigilant and protect your online presence, so let's get started.

Identifying the Programming Language

Before we can inject code, we need to determine the programming language used by the website. By examining the IP address and file extension, we can quickly identify the language. In this case, the website is running on PHP.

Using a tool called Webalyzer, we can scan the website and confirm the programming language. In this case, it is PHP.

Code Injection Attack

Now that we know the website is vulnerable to code injection, we can proceed with the attack. The website has input fields where we can enter our malicious payload. By crafting the right payload, we can execute shell commands to gain control of the server.

One of the key areas to target is the "reflecting back your message" feature. By changing the message input to include our payload, we can see the result of the injection. In this case, we successfully executed a PHP command and obtained information about the PHP version.

Furthermore, we can use commands like "system who am I" to find out the user operating the server and "PWD" to determine the current working directory. By exploring the directories, we might discover sensitive information like passwords.

Remote Control of the Server

Once we have gained execution rights on the system, we can take control of the server remotely. With commands like "ls -l" and "cat bw.sql", we can view the contents of directories and files.

If we come across a SQLite file, we can use a tool like DB Browser for SQLite to browse its data. This allows us to access information stored in the file, such as usernames and passwords.

For even more advanced control, we can use a tool called Comics. This tool enables us to remotely control the computer in a more sophisticated manner. By providing the target URL and the necessary cookie value, we can exploit the system and gain full control.

With this level of access, we can execute various commands and navigate through the system. We have successfully achieved remote control of the entire computer using the Comics tool.

Conclusion

Injecting code into a website for remote control can be a powerful technique for hackers. By identifying the programming language and exploiting code injection vulnerabilities, they can gain full control of the server. It is crucial to stay informed about these vulnerabilities and take necessary precautions to protect your website.
