How to find Vulnerabilities on my Server?

Host administrators who need to find vulnerabilities on their servers need a tool to help them accomplish this task. There are many web application security tools that do just that.

As the server administrator, it is your responsibility to install the most effective web application security software on your servers. However, as a web application developer, I believe that you should use a well-known and highly secure toolset. It’s just common sense.

I want to know how to find vulnerabilities on my server using privilege escalation with msf. I can find security vulnerabilities in source code of a website that is running on my server or on any other software.

I will start with the vulnerabilities of web applications. By vulnerabilities I mean vulnerabilities that could enable a remote attacker to take control of the target computer.

After that I will look at flaws in programs that are running on the target machine. So that means they are vulnerable to SQL injections, CSRF attacks and many other type of vulnerabilities.

What if I can find a vulnerability on a website?

Very simple. Let's say I can find a security flaw in a website that is running on my server. In order to find it, I need to use a reverse web exploit.

In order to write a web exploit, I need a vulnerable website. I cannot find such a website.

Well, not quite. Even if I can't find such a website, I still can find security flaws in it.

And then use a vulnerability to attack the website on my server.

Okay, let's say that I can find a security flaw in a website that is running on my server. I could take a vulnerable website and use it to attack other websites.

So, I can find a security flaw in a web application and use it to attack a website that I find later on.

Problem: How can I find a security flaw?

Well, the first problem is the one of finding a security flaw. Luckily, there is a common technique for this. It is called a scanning technique.

A vulnerability scanning technique is basically a scanning tool that you can use to look for flaws in a website.

There are several scanners for this purpose. 

If you want to know which flaw to use to find vulnerabilities in a particular website, it is best to look at that website.

You have to take advantage of what that website has to offer. If the website is vulnerable, you will get a report on the security flaw it found.

If you can't find the flaw, it's best to look at other websites.

You can look at a specific report on a specific flaw that you found using one of the scanners for this website.

This is the perfect place to look for vulnerabilities if your website doesn't offer a scanner of its own.

Yes, I know that this method is not 100% secure but it works and that's all that matters.

It is for researchers and you should use that information for defensive purposes. What you should do with this data is write an exploit that will use that flaw to compromise a web server.

Sometimes, you can find multiple flaws in the same website.

For example, maybe the web application does not make use of an anti-exploit.

This flaw can be used to attack the website and become a remote attacker.

The only way to find such flaws is by using a scanner.

If you can't find a security flaw, it is better to use an exploit.

Solution to the problem: How to find a vulnerability?

There is a lot of ways to do this.

Analyze the webpage

There are many things that you can do to analyze the webpage. The first thing you can do is to look at the requests that the webpage makes. I usually do this in the security section of a browser.

I also have a PHP application on my server that allows me to analyze the requests that the webpage makes. The disadvantage of using a website is that you cannot do all the analysis there but you can do a lot of it here.

It is much easier to identify a vulnerability in a website if the website is available. Most people don't want to run a vulnerability check on their own server. This means that you have to find the website's address on the Internet. The first step is usually to go to Google and type in the URL of the website you are interested in.

To see the request the webpage makes, I use a simple script that runs in the background while I'm working on a website.

The script first checks if the website is already in Google. If it is, then it waits. It has a very good support that you can use to help with the analysis of the response body.

After that, it checks if the request was sent to a web server. If it is, then it checks if the response is hosted on a web server. If it is, it checks the company name of the web server to see if the web server belongs to the company I'm running the script on.

Once all these checks are done, the script sends a request to a vulnerable web server, waiting for a response.

The script uses several different methods to send a request to a website. I use HTTP POST requests to make sure that the URL that it sends as the query parameter is really a URL of the website. It is a good idea to know what is the URL that you're requesting to check before sending a query. If you don't know, it is better to send a GET request.

In case the vulnerability is found and the URL that you're trying to exploit was actually correct, then the script sends a GET request to the website and performs an "GET" request. The second request performs an "PUT" request to write the exploited page.

The script then sends a "GET" request to Google to check if there is a vulnerability. If there is one, it writes the page and looks at the result of the "GET" request. If there is no vulnerability, then it closes the file and sets the URL variable so that you can use it to identify other vulnerable sites.

You should now know how to get a vulnerability scanner. It is a big responsibility that comes with the script because you have to be extremely careful with what you're doing. The script runs on the local computer and it has to be safe. To be safe, I put it on a system that I don't have access to and I control. You can do the same but only if you have access to the remote system.

Another thing that I usually do is to automate the test and run it manually when I am done with the analysis. You can do this as well but there are too many ways to do it. 

There are a lot of tools available to analyze the vulnerable websites. In the past, I've tried most of them but I found that you get better results when you use a single tool that will automate the whole process.
