Equip your developers with relevant knowledge on OWASP Top 10 vulnerabilities

OWASP top 10 offers the most important guidelines for building and maintaining software with better security practices. When it comes to protecting our businesses, understanding these threat vectors can lead to a more systematic approach. But it also alerts us to the fact that security doesn’t stop here. At Avatao, we compiled several exercises that help our clients take a deeper look into the most popular vulnerabilities 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 in order to identify as other users.


3. Sensitive data exposure

Sensitive web application data, such as financial information, which is weakly protected or not encrypted, can be stolen 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 expose internal files using the file URI handler and 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, due to restrictions not being properly enforced, allows attackers to gain access to restricted resources by tricking authorization mechanisms.

6. Security misconfiguration

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

7. Cross-site scripting (XSS)

Successfully executed XSS attacks allow malicious actors to masquerade as legitimate 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, leading to a variety of attacks.

10. Insufficient logging and monitoring

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