Ping exploit program

A command injection vulnerability is exploited by adding injecting a command. There are two main ways to accomplish this in a Linux environment:. Using an operator to string multiple system commands together is the most well-known method to achieve command injection. The following is its pseudocode implementation:.

The shell would receive the input ping 8. However, what if inputIPAddress was something else, like 8. In that case, the shell would receive the following input:. Because ; is a symbol for separating commands, the shell would execute two separate commands in succession:. This is a fairly benign example, but using the same technique, an attacker could steal confidential information, or create a backdoor into the server. There are a few details to be aware of when using the above method.

Building upon the previous example, what if the program has some additional flags for handling timeouts at the end of the shell command?

However, the fix for this is simple. All the attacker has to do is add a comment to the injection. In that case, the payload is:. The interpreter ignores comments, so the -c 4 -W 5 will be ignored:. The takeaway is that if you use this method to exploit a command injection vulnerability, then you should add a comment to the end of the payload.

That way, you can avoid syntax errors. A less common, but often more reliable method you can use to exploit a command injection vulnerability is command substitution. Command substitution is a feature of the shell language that allows you to execute a command and have the output of that command replace substitute text in another command.

An example should make this concept easy to understand:. As you can see in the command substitution example, the whoami command was executed, and the result was substituted into the main command. It is a simple ping monitoring tool that allows you to ping multiple hosts or websites at a time.

Not only it can ping multiple hosts, but it also lets you monitor ping status in real time like ping time, response time, etc. Before starting the ping sending and ping monitoring process, you need to configure this software. You can use its Config section to do that. Apart from setting up the host, you can also set sound and email alert in case of some connection error, using its Config section.

It is a great ping monitoring software that shows you important ping monitoring data in real time. Visual Ping monitor is another free ping monitoring tool for Windows.

With the use of this software, you can send ping to three hosts at a time and track their responses. The main aim of this tool is to compare the ping response times of three different hosts. However, you can also manually add a lot of host websites in it and switch between them. Apart from response time, this tool also shows the ping speed of different host websites. It is a powerful ping monitoring software that allows you to monitor multiple hosts at a time. Plus, graphs to visualize different types of monitoring data is also provided by it.

In this free version of this software, you can only monitor up to 5 hosts at a time. Plus, options to manually configure ping interval, gateway configuration, etc. It is another really good ping monitoring software that shows every possible ping monitoring information.

However, it also imposes some restrictions. Free Ping Tool is the next free ping monitoring tool for Windows. In it, you can manually add and monitor multiple host websites at a time.

The process of adding a new host and pinging to hosts is simple in it. First, enter the website name hostname in the Host field and press the Add button.

After that, press the Start button to start the ping monitoring process. It is one of the best free ping monitoring tool through which you cannot only monitor ping data but also monitor other important parameters like Traceroute, Web Response, etc. Ping Monitor is a free open source ping monitoring tool for Windows. In order to run this software, your system needs to have.

NET framework. It is a straightforward ping monitoring tool through which you can ping one host at a time and track its response.

It is mainly used to check the host connectivity. It is a very basic ping monitoring tool through which you can check host connectivity and monitor data that this tool provides by sending multiple pings to a host. Skipole Monitor is a free open source ping monitoring tool for Windows. Using this tool, you can easily ping multiple hosts and find out their status. This sensor shows the statistical jitter value and the execution time of requests.

Monitoring for jitter is especially important in environments with important services like VoIP phones. However, those with larger networks will need to purchase one of the paid versions. Pingdom is a ping monitor for websites. The only way to be sure that everyone everywhere can get to your site is to test access regularly from many locations around the world.

Ping is the ideal tool for performing these checks. The Pingdom system operates on servers in more than 1, locations around the world. Even the dashboard is hosted on the cloud. The service is a little more sophisticated than just a recursive ping execution.

It judges response times for sites that are still accessible, so you can get a range of performance metrics out of the service. The system includes alerts that arise when response times drop or when a testing location is unable to get through to the site.

As well as displaying the alert, Pingdom will send out a notification by SMS or email. Pingdom also has an API that funnels alerts, so you can integrate those notifications into any custom application. Once a problem is detected, the Root Cause Analysis module will perform tests, such as traceroute to work out exactly why the site is unavailable or slow.

Pingdom is a subscription service and the price is set on a menu with a rate for the number of Synthetic Monitoring actions that you select plus a price for the number of Real User Monitoring credits that you choose.

However, there is an Enterprise plan available, which is a customized package and that would enable you to subscribe to just one of those two services. You can assess the service with a day free trial.
