Top 5 Issues Faced in Asp.Net Application

Do you think that the security of web apps is all about your website being hacked or gathering confidential data from websites, delivering high traction to websites with a refutation of any types of attacks such as viruses, worms, and Trojan horses? Well, the answer is no. There are other issues that are regularly unnoticed.

The motive of this article is just to give you insight on different sections that a web-developer faces when he/she is designing a website. This article is not only helpful for new developers but also for the experienced ones. This way they will be able to make the website secure and easy to work on. If you follow and understand these errors, you get your attention on the key strategy and execution adoptions that will have an impact on your application’s safety.

1- Cross Site Scripting (XSS): This weakness allows the hacker to insert some mischievous code while entering data. It could any code such as JavaScript code, VB script, or any additional script code. By default, ASP dot NET MVC authenticates the inputs and gives a server fault or server error in case of the script.

2- Cross-site resource forgery (CSRF):  CSRF (also known as one click attack) is a type of dangerous bout where illicit information come from a reliable website where the user is verified. For example, say the operator logged into an application with windows/cookie based verification. Now without logging off, the operator checks out a mischievous website and accesses any page. This website will then send off a request through your website for carrying out a corrupt process. Before being verified it will be reflected as legal demand because the request is valid.

Our motto is to spread the awareness about the latest technological happenings and the best-in-the-business news, to engage our users and startup customers from storytelling in setting up the startup culture.

MVC provides AntiForgeryToken tool to evade any such CSRF attacks. For that, you will require an AntiForgeryToken aid in view which will look as


3- Handling Errors Properly: Errors will happen and no matter how hard you try, they will discover a way to come to the user. In case they are not handled strategically and efficiently they can disclose core data to third parties causing risk to the website. Following YSOD or fatal error is often seen when an unhandled compromise happens:

Might not seem big but it reveals internal code, physical file structure, stack trace, and the version of [tweetme via=”” tags=”ASPdotNET, dotnetdeveloper, WebAppDevelopers” url=””]ASP.NET Development[/tweetme] and .NET framework.

4- SQL Injection: SQL injection is a popular safety weakness and it yet not handled appropriately in a lot of applications. SQL injection permits the attackers to interfere with current figures, amend transactions, or also scrap the information or archives. This leads to terrible loss to the business.

Using this method, the attacker inserts some mischievous SQL commands via input. These commands have the liberty and authority to alter the SQL command running on the server.

5- Click-Jacking: Click-Jacking is another major defenselessness that gets unnoticed generally. In this, the hacker uses an invulnerable protection to puzzle the operator so that they can click on a key or link on the different page while they are envisioned to click on the most important page.

To evade this problem, we should not permit any website of the changed domain in iFrame to operate. To attain this, we need to add a response code header X-FRAME-OPTIONS as deny or same origin.


So what is the takeaway from this post? Security is important for any web application, and if not controlled appropriately, it can damage the business expressively. We discussed five of the most usual weaknesses of ASP dot NET application and these can be rectified by doing some configuration change or trivial code alterations.
