Web App Penetration Testing: 5 common vulnerabilities and how to address them

Websites and web apps are essential tools for many businesses, but their centrality makes them an ideal target for cyberattacks. Identifying and addressing vulnerabilities through web penetration testing is crucial to keep the business secure. Here are the five most common vulnerabilities and how to address them:

1.   Injection (SQL, Command Injection)

   Injection vulnerabilities, such as SQL injection, allow attackers to insert malicious code, compromising sensitive data and system integrity. The solution? Implement robust input validation and use parameterized queries to minimize risks.

   Web penetration testing helps uncover these issues before it’s too late, allowing you to take action to ensure solid protection.

2. Cross-Site Sc ripting (XSS)

   XSS attacks allow hackers to execute malicious scripts in users’ browsers, stealing sensitive information or altering visible content. To prevent these attacks, it’s crucial to implement thorough input sanitization and configure the proper HTTPS headers.

   For more robust web app security, check if your XSS protections are adequate through specific testing.

3. Broken Authentication e Session Management

   Flaws in authentication and session management mechanisms open the door to unauthorized access. Implementing technologies like multi-factor authentication (MFA), secure cookie management, and ensuring robust APIs are essential solutions to reduce risks.

   With targeted testing, you can verify if your systems are ready to withstand more sophisticated attacks, ensuring the security of your users and business data.

4. Insecure Direct Object References (IDOR)

   This vulnerability occurs when an application allows users to access resources without proper authorization. Implementing server-side access controls is essential to protect your business’s critical data and resources.

   Web penetration testing is the ideal solution to identify these flaws, helping you fix them before they can be exploited.

5. Insecure configurations

   Default settings, outdated software, or accessible directories are common but often overlooked issues. Automating configuration processes and limiting exposed information are essential steps to strengthen security.

   Not sure where to start? A thorough test of your configurations can help identify weak points and improve your protection.

Don’t leave room for vulnerabilities.

Web penetration testing doesn’t just identify vulnerabilities like the ones described above: it also provides concrete guidance on how to eliminate them and protect your business from future risks. Acting proactively ensures your web app security is up to the challenges of the digital landscape and compliant with legal regulations.
