This non-profit foundation works to improve software security. They have published a top 10 list that acts as an awareness document for developers. It represents a broad consensus about the most critical security risks. Server-Side Request Forgery (SSRF) flaws occur whenever a web application
fetches a remote resource without validating the user-supplied URL. It allows
an attacker to coerce the application to send a crafted request to an unexpected
destination, even when protected by a firewall, VPN, or another type of network
access control list (ACL). OWASP Practice is a virtual environment to help people who want to begin their journey into web application security.

SSRF flaws occur whenever we fetch a remote resource without validating the URL supplied by the user. Insecure design represents different weaknesses, expressed as “missing or ineffective. I started with the “Input Validation” and “Parameterized Statements” lessons.

Security Logging and Monitoring Failures

The longer an attacker goes undetected, the more likely the system will be compromised. Once developers know how to build a secure thing, they need to understand how to do so in concert with others. The broader picture of this is the OWASP Lessons maturity level of the team performing all the security aspects of the greater SSDLC – and when we say SSDLC at OWASP, we mean OWASP SAMM. Involvement in the development and promotion of Secure Coding Dojo is actively encouraged!

Below are vulnerabilities that were included in the 2013 or 2017 OWASP Top 10 list
that were not included in the 2021 list. These vulnerabilities are still relevant
but were not included in the 2021 list because they have become less prevalent. If you are using the .NET Framework, you can find some code snippets here.

OWASP Top 10

I prevented the injection by using a parameterized query with placeholders instead of concatenating user input. Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when
untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing
unintended commands or accessing data without proper authorization.

The Secure Coding Dojo is an interactive training platform that teaches secure coding practices through lessons and challenges. It was initially developed by Trend Micro and donated to OWASP in 2021. Software and data integrity failures relate to code and infrastructure that does not protect
against integrity violations.

IHtmlHelper.BeginForm also sends anti-forgery-tokens automatically. Starting with .NET Core 2.0 it is possible to automatically generate and verify the antiforgery token. Make sure the tokens are removed completely for invalidation on logout.
