10 Most Common Website Vulnerabilities

Websites are one of the most important online assets of any business or organization. Unfortunately, your site may be subjected to countless vulnerabilities without any significant alerts. See our top 10 list.

Here are some of the most common website vulnerabilities:

  1. SQL Injection Flaws:

Injection flaws occur due to the filtering of untrusted inputs. It can happen when you pass unfiltered data to the SQL Server (SQL Injections), or anywhere else. The main vulnerability is that the attacker can inject commands in these entities, and as a result, there can be loss of data and hijacking of the user's browser.

  1. Broken Authentication:

Many problems can lead to broken authentication vulnerability. Few pitfalls are listed below:

  1. The website URL can contain a session ID leak

  2. The password might not be encrypted

  3. The session may be predictable

  4. Session fixation maybe be possible

  1. Cross-site Scripting:

It is one of the most common ways used by the attackers to manipulate or hack a web application. In cross-site scripting, the attacker uses Java-Script Tags on inputs. When the data is returned to the user's end, the user's browser executes the data. Consequently, a link is generated between attackers and users, which can be a disaster for the web application.

  1. Insecure Direct Object Reference:

Weak Direct Object Reference means that the internal object or key to the database is exposed to the user. Thus, an attacker can also access the database information, which will be a problem for the website.

  1. Security Misconfiguration:

The common reason for a system to get exposed to vulnerability is security misconfiguration. Some of the security configuration mishaps are listed below:

  1. During the production period, the application is running in debug mode

  2. Direct listing enabled on the server results in loss of data

  3. You are using outdated software

  4. You are Running unnecessary applications

  5. You are not changing the default keys and passwords

  6. Sensitive Data Exposure:

It happens when the data is not encrypted. The confidential data, like credit card information, passwords, keys, etc. can get exposed to hackers. Remember that all of this data is sensitive data, and it should always be stored using encryption.

  1. Failure to restrict URL access:

Web application checks URL access rights before entering the protected links and buttons. Web applications are designed to repeat these checks when the pages are requested to access.

Due to the same repetition of checkpoints, a good guess attacker can log in to privileges pages, view the sensitive pages, and access confidential information.

  1. Insufficient Transport Layer Protection:

It deals with the transfer of sensitive data like credit card number, login key, password, or any other confidential data across the network.

By using weak techniques or applying less effective protection algorithms, you will expose the sensitive data to the attacker due to the lack of security.

  1. Invalidated Redirects and forward:

As users of the internet, we always go from one page to another. The web application should always validate a redirect or a forward to the targeted page. If the validation is not done correctly, an attacker can easily use this opportunity to attack the website.

  1. Cross-Site Request Forgery:

A cross-site request forgery happens when a malicious website, e-mail, or a program manipulates the user's browser to attack a trusted website on which the user is currently logged in or authenticated.

The attacker sends a link. The user clicks the link, and just like that, the attacker has access to your browser.
