Website vulnerabilities are weaknesses or flaws in a website’s design, implementation, or configuration that can be exploited by hackers to gain unauthorised access, steal data, disrupt services, or perform other malicious activities.

Understanding these vulnerabilities and how they can be exploited is crucial for securing your website against potential attacks. This article will delve into common website vulnerabilities and the methods hackers use to exploit them.

Common Website Vulnerabilities That Hackers Can Exploit

Here are the top website vulnerabilities that hackers can exploit:

1. SQL Injection (SQLi)

SQL Injection occurs when a hacker injects malicious SQL queries into a website’s input fields, such as search boxes or login forms. These queries can manipulate the database to reveal sensitive information, modify data, or even gain administrative access.

Exploitation:

  • A hacker enters a specially crafted SQL query into an input field.
  • The query is executed by the database, allowing the hacker to access or modify the data.

2. Cross-Site Scripting (XSS)

XSS vulnerabilities arise when a website allows users to inject malicious scripts into web pages viewed by others. These scripts can hijack user sessions, steal cookies, redirect users, or perform other malicious actions.

Exploitation:

  • A hacker injects a malicious script into a comment or form.
  • When other users visit the page, their browsers execute the script, which can steal their session data or perform other harmful actions.

3. Cross-Site Request Forgery (CSRF)

CSRF attacks trick users into performing actions they did not intend to perform. This is done by sending a request from an authenticated user to a website where they are logged in, without their knowledge.

Exploitation:

  • A hacker sends a malicious link or embeds a request in a website.
  • When an authenticated user clicks the link or visits the website, the request is executed without their consent.

4. Remote Code Execution (RCE)

RCE vulnerabilities allow hackers to execute arbitrary code on the server hosting the website. This can lead to complete server compromise, data theft, and other severe consequences.

Exploitation:

  • A hacker finds a way to upload or inject code that the server executes.
  • The executed code can give the hacker control over the server.

5. File Inclusion Vulnerabilities

These vulnerabilities occur when a website improperly includes files, allowing attackers to include remote files through the web browser. This can lead to RCE or the disclosure of sensitive information.

Exploitation:

  • A hacker manipulates the input to include a remote file.
  • The server processes the file, potentially exposing sensitive information or allowing code execution.

6. Insecure Direct Object References (IDOR)

IDOR occurs when an application exposes internal implementation objects, such as files or database keys, allowing users to manipulate them to access unauthorised data.

Exploitation:

  • A hacker changes a URL parameter to access restricted information.
  • The server returns the unauthorised data due to improper access control.

7. Security Misconfigurations

Security misconfigurations include any security settings that are not set up correctly, leaving the website vulnerable to attacks. This can range from default credentials being used to enabling unnecessary features.

Exploitation:

  • A hacker scans the website for common misconfigurations.
  • The hacker exploits these misconfigurations to gain unauthorised access or perform other malicious actions.

How Hackers Exploit Website Vulnerabilities?

Hackers often use automated tools to scan websites for known vulnerabilities. These tools can quickly identify weaknesses in the website’s code, configuration, and components.

  • Hackers use phishing emails and social engineering tactics to trick users into providing sensitive information or performing actions that compromise the website’s security.
  • Brute force attacks involve systematically trying numerous combinations of usernames and passwords to gain unauthorised access to a website.
  • Websites often use third-party plugins, libraries, and frameworks. Hackers exploit vulnerabilities in these components to compromise the website.
  • Session hijacking involves stealing a user’s session token to impersonate them and gain unauthorised access to the website.
  • In these attacks, hackers intercept and alter communication between the user and the website to steal data or inject malicious content.
  • DNS spoofing redirects users from a legitimate website to a malicious one, allowing hackers to steal data or distribute malware.
