The Importance of the OWASP Top 10
Web app vulnerabilities are not minor concerns. The 2017 Equifax breach exposed 147 million records due to a failure to patch a known vulnerability (CVE-2017-5638). The OWASP Top 10 prioritizes the most critical risks in web applications, aiming to make the web safer by educating developers and security pros.
1. Broken Access Control
Unauthorized data access is a serious issue. Facebook's 2019 breach allowed attackers to access over 419 million user records. How to test: Use Burp Suite to check if restricted pages can be accessed without proper authorization.
2. Cryptographic Failures
The Heartbleed bug was a cryptographic failure that exposed sensitive data by allowing attackers to read server memory. Secure encryption is vital. What not to do: Avoid outdated or weak encryption algorithms like MD5.
3. Injection
SQL injections remain relevant due to their impact. The 2014 TalkTalk breach cost the company £60 million. Here's how to test: Use sqlmap to identify exploitable injection points.
4. Insecure Design
Insecure design flaws affect system architecture. The MOVEit breach demonstrated how insecure default settings can expose sensitive data.
5. Security Misconfiguration
Misconfigurations are easy targets. The 2019 Capital One breach involved an exposed S3 bucket leading to data theft. To test: Regularly scan your infrastructure with tools like nmap for open ports and default credentials.
6. Vulnerable and Outdated Components
The Equifax breach exemplifies the dangers of outdated components. Failing to update Apache Struts led to disaster. What to do: Maintain a detailed inventory of components and update them regularly.
7. Identification and Authentication Failures
Weak authentication opens doors for attackers. Testing tip: Use brute-force tools like Hydra to test the strength of your authentication mechanisms.
8. Software and Data Integrity Failures
Supply chain attacks, such as SolarWinds, highlight the risk of blindly trusting third-party software. Action step: Verify the integrity of updates and third-party software using checksums.
9. Security Logging and Monitoring Failures
Without logging, you're flying blind. The 2013 Target breach could have been mitigated with prompt attention to security alerts. How to improve: Implement comprehensive logging and real-time monitoring using tools like Splunk.
10. Server-Side Request Forgery (SSRF)
SSRF attacks can trick servers into making unauthorized requests. Testing method: Use ffuf to identify SSRF vulnerabilities by fuzzing URL parameters.
