All about Cross-Site Scripting

1 Alert 501337

Have you ever heard about ‘1 alert 501337’? or have you ever heard about cross-site scripting? Well, the script is actually a part of client-side scripts that are meant to exploit a type of web application security vulnerability that is known as cross-site scripting or XSS. First of all, do you guys already know what is the so-called cross-site scripting or XSS? Actually, it is not rocket science but some might know nothing about cross-site scripting. Well, if you people have not known yet then there is no need to worry because in this article we will provide you with important information about cross-site scripting that you guys might be desperately looking for. Let’s check this out.

Cross-Site Scripting In a Nutshell

First thing first, for those who do not know about cross-site scripting (XSS) or the code ‘1 alert 501337’ might want to pay attention to this section since it is fundamental and important before you move to the bigger things. Cross-site scripting or often abbreviated to XSS is one of many vulnerabilities of computer security that is usually found in web applications. This vulnerability usually exploited by hackers who want to do malice or terror. Those who exploit cross-site scripting usually aim to bypass web application security. The harm is done by injecting certain scripts that are meant for client-side into web pages. Later, the users who visit the web pages will view these scripts that are meant to wreak havoc. Cross-site scripting or XSS is still known as one of the most dangerous threat vectors that threaten web applications. The damage that is may be caused by cross-site scripting or XSS varied a lot. It is ranging from minor trouble to serious security threat. The history of exploitation of cross-site scripting can be traced back to the 1990s. Many important sites such as Facebook, YouTube, MySpace, and Twitter was even threatened by the exploitation of XSS vulnerabilities. As of 2007, from all of the security vulnerabilities that have been documented, more than half of it is cross-site scripting. Some researchers even found that 70% of websites are prone to the exploitation of XSS vulnerabilities.

Usually, web security relies on some sort of mechanism. However, it turns out that thing becomes a vulnerability of web applications that might be exploited by attackers or hackers to deliver malevolent content. After exploiting the mechanism on which website security relies on, the attackers or hackers get access to injecting the malevolent content that will be seen by other users. The content that is delivered by the hackers or attackers are also considered sent from a trusted source and permitted to be shown. The hackers can also gain access to important things such as session cookies or content of a page that is sensitive through users. This major vector threat is also known as a code injection case which means invalid data is processed which caused a computer bug, this very bug is then exploited by attackers or hackers.

How to Prevent the Attacks

Now that you know the history of cross-site scripting which one of the codes is ‘1 alert 501337’. You might want to know the ways to prevent the attacks. Below is the list of preventive measures that you can take to prevent the attacks.

Additional Cookie Protection

This method of cross-site scripting prevention is used by a lot of people although not so perfect and effective. The method is done by using additional security controls if you happen to handle a user authentication that is based on cookies. Usually, session cookies are used to authenticate by a lot of web applications. Unfortunately, client-side scripts can bypass the security to get to these cookies. Therefore, additional security controls are applied to offer more protection.

Disable the Scripts

One of the most effective ways to prevent XSS attacks is by disabling scripts. Mostly, web applications need JavaScript to operate. However, there are some web applications that do not need client-side scripts to operate. Therefore, the client-side scripts that are meant to wreak havoc cannot be viewed by you if you choose to disable scripting altogether.

Now that you know about cross-site scripting, ‘1 alert 501337’, and everything in between, you might want to share this article with your friends and loved ones.
