Common Web Security Vulnerabilities

Common Web Security Vulnerabilities

Globally, businesses are placing a high priority on cybersecurity, especially when it comes to web applications. Cyberattacks can be initiated by at least three critical vulnerabilities on an average website, according to a recent WhiteHat report.

Your business may lose millions of dollars dealing with various threads. A leak of sensitive information and a system crash can destroy your company’s reputation and destroy your users’ trust. As a result, it’s a good idea to find a way to ensure the safety and stability of your web application.

How can web applications be made more secure? In the face of such threats, how can they be prevented? Here’s what you need to know!

As part of our commitment to providing you with the most helpful, cutting-edge web app security insights, we will use the experience of the E2logy team in web development and quality assurance. Our lesson will teach you how to detect Common Web Security Vulnerabilities, and how to enhance the security of your website.

What are Web Security Vulnerabilities?

A web application or its components or processes can be vulnerable to security risks due to flaws or bugs in its code, system misconfiguration, or other weaknesses. It is possible for attackers to gain unauthorized access to mission-critical assets, systems, and processes through web application security vulnerabilities. It is possible to orchestrate attacks, take over applications, steal data using privilege escalation, and disrupt large-scale services using such access.

Common Web Security Vulnerabilities

There is no way to stay out of trouble even if you are a CIO and a web security expert. Everyone needs to know what to watch out for to stay safe. Security vulnerabilities are some of the most common threats you need to be aware of.

1. SQL Injection

An attacker attacks a web application by using application code to gain access to or modify database content through SQL injection. An attacker can then create, read, update, alter, or delete data stored in the back-end database if this attack is successful. Web application security vulnerabilities commonly occur due to SQL injection.

2. Broken authentication

User access vulnerabilities are also related to broken authentication. The malicious actor in this case compromises identifying information, such as passwords, keys, or session tokens, to confirm the identity of the user. It was the company’s failure to set up adequate controls for identity and access management that allowed the malicious actor to gain unauthorized access to systems, networks, and software.

3. Cross-Site Scripting (XSS)

In XSS attacks, malicious scripts are injected into websites or web applications, similar to SQL injection attacks. Unlike malicious code, browsers run malicious code only when a compromised website or app is accessed. When visitors view a target page (e.g., a JavaScript link embedded on the page), attackers inject code into input fields. Exposure of user information due to an XSS attack will have long-term consequences for a business’s reputation. Users may remain unaware that data sent to the infected app can be stolen by attackers.

4. Cross-Site Request Forgery (CSRF)

Users do not realize they are performing actions for the attacker when they are exploited by CSRF vulnerabilities. Attackers utilizing CSRF can alter, delete, transfer, or send instructions posing the user to steal, modify, or delete funds or send instructions masquerading as the user.

5. Security Misconfigurations

You are at risk of security misconfigurations if security controls are incorrectly configured or left unsecured. It is generally possible to have a misconfiguration on your endpoints when bad configurations are implemented, computer settings are implemented incorrectly, or technical problems occur.

6. Insecure Direct Object References

A third web app vulnerability relates to unauthorized access to sensitive databases through Insecure Direct Object References (IDOR). The URL format or pattern of your website may expose the potential for direct entry into your system. Furthermore, no additional authorization or access control checks are performed. The result is that hackers can bypass authorization easily and gain access to stored data.

7. Insecure Cryptographic Storage

When sensitive data is not stored securely, there exists an insecure cryptographic storage vulnerability. Credit card information, health details, and profile information are all information related to the user. A website’s sensitive data falls under this category. The application database will store this data. Attackers will be able to access this data if it is not encrypted or hashed properly.

8. Directory Traversal

Backtracking attacks exploit how web applications receive data from web servers using directory traversal attacks. Users can access specific files within the root directory of web apps using Access Control Lists (ACLs). The URL format used for file requests by a target application can be identified by a malicious actor.

9. Insufficient Transport Layer Protection

Internet applications securely communicate with each other using transport layer security (TLS). In some applications, TLS is used only for authentication, so when someone uses the application, data and ID session information is exposed. Users’ devices and application servers can be intercepted as they travel across the internet due to this vulnerability.


Keeping up with technology needs and knowing what works for your business are key factors in website security. There are several basic web security vulnerabilities that one might overlook. Keeping your business secure and addressing these vulnerabilities is easier when you are informed and prepared.
