5 most common website vulnerabilities

Website vulnerabilities are security weaknesses or flaws that can be exploited by attackers to compromise the security of the website.. These vulnerabilities may allow an attacker to access, modify, or destroy information, or even take full control of the website. It is important to keep them in mind to know how to avoid hacker attacks.

One of the easiest ways to protect your company from website vulnerabilities is by using analysis methods that can identify weak points in the code. If you are interested in knowing more about it or need more detailed and in-depth information, you can request a consultancy with Codster to solve your doubts about it.

Knowing the most common website vulnerabilities is key to understanding how you can protect yourself from them to maintain a secure environment for your products and services.

Vulnerabilities in websites that could affect your company

As we mentioned, there is a need to know some of the most common vulnerabilities and face them in order to resolve them on time. In this way, both the public you are seeking to approach will have a positive opinion of you and the government could guarantee that you approve the necessary cybersecurity regulations.

There are different types of vulnerabilities in a website, some of the most common and that could put your company at risk are:

Malicious code injection or SQL injection

SQL injection is a type of website security vulnerability that allows attackers to execute malicious commands in a database through unvalidated input into web forms or URLs.

In SQL injection, an attacker enters a malicious query through a web form input field, such as a search box or login input, which is then executed against the website's database. These queries may be aimed at stealing, modifying, or removing sensitive information from the database.

To protect against SQL injection, it is important for website owners to validate and filter all data input received via web forms or URLs to prevent attackers from entering malicious queries. In addition, it is important to keep website systems and applications up to date to correct any known security vulnerabilities.

Cross-site scripting (XSS)

Cross-Site Scripting (XSS) is a type of common website vulnerability that allows attackers to inject malicious code into a web page viewed by other users. This can allow the attacker to steal sensitive information, such as passwords, or redirect the user to a malicious website.

Malicious code can be JavaScript, HTML, Flash, or other code that runs in the browser of the user visiting the website. There are two types of XSS: stored XSS and reflected XSS. Stored XSS occurs when malicious code is stored in the website's database and is displayed to users every time they visit the compromised web page. Reflected XSS occurs when malicious code is reflected on the web page only for the user who executed it.

To protect against XSS, website owners must validate and filter all data input received via web forms or URLs to prevent attackers from entering malicious code. Additionally, security tools such as Web Application Firewalls (WAFs) and vulnerability scanning tools should be used to detect and fix XSS vulnerabilities.

Cross-site request forgery (CSRF)

Cross-Site Request Forgery (CSRF) is a type of hacking attack in which a malicious website tricks a user into performing an unwanted action on another website where they already have an active session. For example, you could include a malicious link or image on a web page that, when clicked, sends a malicious request from the user's browser to another authenticated website, without the user being aware of it.

To protect a website from CSRF, website owners must implement security measures such as random request tokens and HTTP Referer checking to ensure that the request is coming from a legitimate source. It is also important that users exercise caution when clicking on links and downloading files from unknown sources to avoid falling victim to a CSRF attack.

Brute force cyber attacks

A brute force attack is a method used by attackers to discover passwords or access credentials to systems or applications by trying all possible combinations until the correct one is found. This type of attack is based on the assumption that the password is a simple and predictable combination of characters, such as a common word or a date of birth.

The brute force attack is carried out by using computer programs that automate the password testing process. These programs try thousands or millions of password combinations every second until they find the right one. Attackers use this method to access online accounts, servers, devices, networks, or applications.

To protect against these kinds of vulnerabilities on websites, it's important to have strong, unique passwords that contain a combination of letters, numbers, and symbols, and change them regularly. Additionally, security measures such as multi-factor authentication

buffer overflow

Buffer overflow is one of the vulnerabilities in websites that occurs when a program tries to store more data than it can handle in a buffer (an area of temporary memory used to store data). This can occur when data is entered that exceeds the buffer capacity or when a program receives malicious data designed to exploit this vulnerability.

When a buffer overflow occurs, additional data overwrites adjacent memory, which can cause the program to behave unpredictably or even crash. In some cases, attackers can exploit this vulnerability to execute malicious code on the compromised system, which can result in a variety of detrimental consequences, such as data corruption, theft of sensitive information, or remote control of the compromised system.

To prevent the exploitation of these types of vulnerabilities on websites, software developers must take measures to ensure that buffers are correctly sized and that input validation and control mechanisms are implemented. Additionally, intrusion detection systems and firewalls can be used to detect and block attempts to exploit this vulnerability.

web application security it is even more important if you are dealing with confidential and sensitive information. By performing a comprehensive analysis of web application security flaws, loopholes, and vulnerabilities, you also significantly decrease the risks associated with a data breach performed by cybersecurity bad actors.
