Equip your developers with relevant knowledge on OWASP Top 10 vulnerabilities

OWASP top 10 offers one of the most important guardrails for building and maintaining software with better security best practices. The understanding of these threat vectors can lead to a more systematic approach when it comes to protecting our businesses, but also rings a waking alarm that security doesn’t stop here. At Avatao, we compiled several exercises that help our clients take a deeper look into the world of the most popular vulnerabilites reported by the OWASP community.

On the Avatao platform you can find practical exercises covering the most important OWASP Top 10 vulnerabilities, in the most popular programming languages, such as Java, JavaScript, Node.JS, C# and more.

Topics developers can practice through real-life scenarios include:

1. Injections

Injection flaws such as SQL happen when as part of a command or query, untrusted data is sent to an interpreter. The attacker’s data is able to make the interpreter execute unwanted commands, or even access unauthorized data.

2. Broken authentication

When authentication functions of applications are not implemented properly, attackers can easily compromise passwords, session tokens, or keys, and take advantage of other flaws to identify as other users.


3. Sensitive data exposure

Weakly protected, not encrypted sensitive data in web applications, such as financial information, can be stealed or modified by attackers, and used to commit credit card fraud, identity theft, and many other crimes.

4. XML external entities

XML external entities can be used to disclose internal files using the file URI handler, internal file shares, and to launch internal port scanning, remote code execution, and denial of service attacks.

5. Broken access control

Broken access control is a type of vulnerability that allows attackers to trick authorization mechanisms to gain access to limited resources, due to restrictions not properly enforced.

6. Security misconfiguration

Incomplete and rarely updated configurations, open cloud storages, and error messages containing sensitive information most often lead to security issues.

7. Cross-site scripting (XSS)

Successfully executed XSS attack allows malicious actors to masquerade as legit users, and use their privileges for lateral movement and/or sensitive data exposure.

8. Insecure deserialization

Insecure Deserialization exploits the process of transforming structured data (e.g., typically JSON, XML) into objects (e.g. Java Objects).

9. Using components with known vulnerabilities

APIs and applications using components with known vulnerabilities can easily eliminate application defenses and therefore lead to different attacks.

10. Insufficient logging and monitoring

Insufficient logging and monitoring allows attackers to further exploit systems, tamper, extract, or destroy data.

How can we avoid the most common vulnerabilities? If you’d like to learn more about the main security pitfalls that every developer needs to know about, read our CTO’s blog post in which he discusses an unofficial proposal of OWASP Top 10 2021!
