Web Application Vulnerabilities- Enhance Your Security

Breaches occur because of web application vulnerabilities. Those vulnerabilities exist because web applications must be accessible to users on multiple networks. The high level of accessibility creates a larger attack surface, and cyber-criminals are quick to take advantage. Here is a look at some of the most common web application vulnerabilities.

SQL Injection

An SQL injection is a security web application vulnerability where the attacker utilizes an application code to access or corrupt the content of a database. Successful SQL injections enable attackers to read or alter data stored in a database.

Cross-Site Scripting (XSS)

XSS focuses on the users of an application. The user’s browser executes web page scripts. Attackers can control user sessions by executing their malicious scripts since browsers can’t differentiate between safe and unsafe scripts. Among other things, the scripts allow them to send users to the attacker’s websites.

Insecure Direct Object Reference

When a web application shows a reference to an internal implementation object, this can offer attackers access to the user’s data. Internal implementation objects can include directories, database keys, and database records. This is a less noticeable example of web application vulnerabilities.

Broken Authentication and Session Management

A web application will usually create session cookies and IDs per valid session. When the user logs out of the browser or the session is abruptly closed, these cookies should be invalidated. If the cookies are not invalidated, the user’s data will continue to be in the system. An attacker can find and use that data. Personal data is especially vulnerable on public computers.

Security Misconfiguration

There are various kinds of vulnerabilities that can be referred to as “security misconfigurations.” All of them rely on poor maintenance or careless configuration of the web application. Security misconfiguration can give access to private data and completely compromise the system.

Cross-Site Request Forgery

Cross-site request forgery works by tricking a user into performing an action on a trusted site where the user has been authenticated. It occurs when the victim is tricked into visiting the attacker’s website, which then sends a request to a web application to which the user is already authenticated. The result is that the attacker can access the web application through the user’s authenticated browser and perform actions.

There are numerous ways for a cyber-criminal to exploit web application vulnerabilities, but there are also numerous ways to defend against them. Taking the right precautions and using the right tools can help to lower the risk of being victimized by hackers.
