Top 10 OWASP Vulnerabilities in 2021
31 Jul 2021

The OWASP stands for the open web application security project. The OWASP is a system that is non-profitable. The function of the OWASP is to protect the software and web applications. There are hundreds and millions on the web software. This software needs to be protected due to various reasons.

There are many types of open web application security projects. However, in some cases, there can be some OWASP vulnerabilities as well. The vulnerabilities mean some kind of weakness or lack of functioning in the application.

The open web applications security project includes the top 10 vulnerabilities. Today, we will discuss more about the top 10 open web applications security project.

Top 10 OWASP vulnerabilities to know about:

The open web applications security project is very important nowadays. The online available web applications and software need to be protected at all costs. It is because of the increasing risks of cyber hacking and fraud.

The open web applications security project is the first step towards the security of coding. The protection of codes, applications, and software is the priority of the developers. The open web applications also benefit the developer with a boost of confidence.

Web developers also use different tools and technologies to protect the software. The open web applications security project is also known as an online community. This online community is responsible for producing free and articles. These articles are available to everyone for free.

The open web applications security project is the main component of the online community. It offers various ways the protect and securing software and web applications. There can still be problems or vulnerabilities within the security project as well.

Some of the top ten open web applications security project vulnerabilities are stated below. And what is meant by such vulnerabilities are also specified below.

1.      SQLI (SQL injection)

SQL injection is a web security vulnerability. It allows the web attackers which involve interference with the examination of the applications. The attackers mostly interfere within the main database of the application.

The SQLI injection is where the attacker can view the data that cannot be viewed normally. This data can be sensitive and important for the users. The attackers can modify and make changes in the data as well.

These changes and interference of the data can cause a lot of damage to the clients and customers. Which in return can also cause damage and make the downfall of the firm's reputation.


The success in the SQLI attack can allow the access of sensitive and confidential data. Access to confidentiality means having access to credit cards, passwords, and personal details. There has been much breaching of data through the SQLI injection.

2.      XSS (Cross-site scripting)

The XSS cross-site scripting is also a type of OWASP vulnerability. This vulnerability gives access to the attackers to lower the site interaction. By lowering the site interaction with the community, there can be a lot of loss.

Cross-site scripting is a type of injection. In which the viral files and data are transferred into the trusted and protected sites. Such problems are quite widespread and can occur almost anywhere in a web application.

The attacker might use the XSS cross-site scripting and send corrupted codes and messages. Making it look like coming from authentic and trusted websites.

3.      CSRF (cross-site request forgery)

The CSRF cross-site request forgery is another vulnerability in the OWASP. It allows or gives the attackers access to make the users do actions which they did not do. The attackers are most likely to use the cross-site request forgery for the websites interfering with each other.

The attackers can make the users perform actions unintentionally too. By sending messages or notifications for changing passwords or making some kind of transactions. It allows the attackers to take control over the whole functionality of the users.

4.      DDOS (Distributed Denial of service) attacks

The DDOS stands for distributed denial of service attacks. It is a fraud attempt to make changes in the normal traffic and server. It can divert the website traffic by disturbing the target server.

Such attacks are carried out when the computers with the internet are connected. Then these networks are controlled by the attackers. Which are infected with viruses or malware. This also gives the attackers the chance to track the user's IP address.

5.      Broken access control

The broken access control is the destruction of access control. The broken access control occurs due to the lack of security measures. The exploiting of sites and sensitive data can be very easy if the access control is hacked by the attackers.

To prevent the broken access control, there should not be any IDs. It is because the IDs can be insecure which can be easily accessed by the attackers. There should be a web application security policy to prevent broken access control.

6.      Insecure deserialization

Insecure deserialization is also a type of OWASP vulnerability. It occurs when untrusted and unknown data is used. The unknown data can be used for denying the DoS attack, denial of service attack.

It gives them access to the codes, authentication and defames the manufacturing logic of an application. By using such ways, the attackers can inject the victim's system with corrupt data and files. The insecure deserialization can be prevented.

It can be prevented by monitoring the deserialization process. And make sure if the serialization processes are secured and encrypted. The use of a firewall can also prevent such attacks.

7.      Sensitive data exposure

The sensitive data exposure is also an OWASP vulnerability. A lot of times the web applications do not protect the data properly. The data can be categorized as healthcare, account information, and financial data.

Such poor security measures can cause the exploitation of the data by web hackers. The attackers can change or modify the given open data. And can cause fraud and false activities as well.

8.      Security misconfiguration

The other most common OWASP vulnerability is security misconfiguration. This occurs due to the common issues lying within the configuration. This can be the result of default configuration which are unprotected.

Open cloud storage and full unsecured access to the data can also cause such issues. Therefore, it is important to protect the operating systems and applications as well.

9.      Insufficient logging and monitoring

Insufficient logging and monitoring allow the attackers to get access to the user's systems. It allows the attackers to attack the systems further as well. This also enables them to exploit and destroy the secured and stored data.

Such breaching of data has been done multiple times. And it is important to take all the safety and security measures.

10.    Using unsafe components

The use of unsafe or vulnerable components can be an issue too. The vulnerable components include libraries, frameworks, and various types of software. Such components are already sensitive and unprotected.

Using them can make it very easy for attackers to exploit your data. Thereby, the protection of sensitive data and stopping the use of vulnerable components should be the first priority.

The above-specified points tell the Top 10 OWASP vulnerabilities.
