Broken authentication vulnerabilities can be mitigated by deploying MFA methods, which offer greater certainty that a user is who they claim to be and prevent automated and brute-force attacks. These vulnerabilities can also be prevented by ensuring developers apply best practices to website security and are given an appropriate period of time to properly test codes before applications are put into production. F5 WAF solutions combine signature and behavioral protections, including threat intelligence from F5 Labs and ML-based security, to keep pace with emerging threats. It eases the burden and complexity of consistently securing applications across clouds, on-premises, and edge environments, while simplifying management via a centralized SaaS infrastructure. For over two decades, it’s been supported by a global network of corporations, foundations, developers, and passionate volunteers.

Security misconfigurations can be prevented by changing default webmaster or CMS settings, removing unused code features, and controlling user comments and user information visibility. Developers should also remove unnecessary documentation, features, frameworks, and samples, segment application architecture, and automate the effectiveness of web environment configurations and settings. Protecting sensitive data is increasingly important given the stringent rules owasp top 9 and punishments of data and privacy regulations, such as the European Union’s General Data Protection Regulation (GDPR).

What is the Open Web Application Security Project (OWASP)?

Common misconfigurations also include failing to patch software flaws, unused web pages, unprotected directories and files, default sharing permissions on cloud storage services, and unused or unnecessary services. “The initial goal of OWASP was to create a platform where security experts could share knowledge, tools, and best practices to improve web application security,” says Jim Mercer, program vice president, software development, DevOps, and DevSecOps at IDC. The problem is that it can be challenging to find impartial advice and practical information to help companies develop their application security (AppSec) programs, especially with the growing challenges and risks posed by open-source software repositories.

• The list serves as a guide for developers, security professionals, and organizations as they prioritize their efforts in identifying and mitigating critical web application security risks.
• Of the 15 projects evaluated, 10 reached successful completion, three are still working on the final deliveries with extended deadlines, and two unfortunately not making the finish line.
• From customer-facing e-commerce platforms to internal tools that manage finances and customer relationships, these applications hold the key to operational efficiency and success.
• This includes bad session management, which can be exploited by attackers using brute-force techniques to guess or confirm user accounts and login credentials.
• The OWASP Top 10 is important because it provides a common language that a security person can quickly understand about what they should worry about, says Janet Worthington, senior security analyst at Forrester Research.

F5 supports the OWASP Foundation and its dedication to improving software security and raising awareness of web application security risks and vulnerabilities. F5 Web Application Firewall solutions block and mitigate a broad spectrum of risks stemming from the OWASP Top 10. OWASP maintains a list of the ten most critical web application security risks, along with effective processes, procedures, and controls to mitigate them. OWASP also provides a list of the Top 10 API Security Risks to educate those involved in API development and maintenance and increase awareness of common API security weaknesses. F5 also offers solutions to address the risks outlined in OWASP’s Automated Threats to Web Applications Project. Distributed Cloud Bot Defense maintains effectiveness regardless of how attackers retool, whether the attacks pivot from web apps to APIs or attempt to bypass anti-automation defenses by spoofing telemetry or using human CAPTCHA solvers.

Access control refers to the specific data, websites, databases, networks, or resources that users are allowed to visit or have access to. This enables attackers to bypass access restrictions, gain unauthorized access to systems and sensitive data, and potentially gain access to admin and privileged user accounts. The OWASP Top 10 is a report, or “awareness document,” that outlines security concerns around web application security. It is regularly updated to ensure it constantly features the 10 most critical risks facing organizations. OWASP recommends all companies to incorporate the document’s findings into their corporate processes to ensure they minimize and mitigate the latest security risks.

• These changes included the integration of the 2017 risk threat XML External Entities (XXE) into the 2021 Security Misconfiguration category and adding 2017 Cross-Site Scripting (XSS) to the 2021 Injection category.
• The OWASP Top 10 is a widely recognized list of the most critical web application security risks.
• F5 Web Application and API Protection (WAAP) solutions defend the entirety of the modern app attack surface with comprehensive protections that include WAF,  API Security, L3-L7 DDoS mitigation, and bot defense against automated threats and fraud.
• As a community-driven project, OWASP brings together experts and enthusiasts to collaborate on improving web application security, helping to build a security-conscious culture that promotes secure coding practices and secure development methodologies.
• Sensitive data, like credit card information, medical details, Social Security numbers, and user passwords, can be exposed if a web application does not protect it effectively.

Deliver and Secure Every App

This collaborative and survey-driven approach allows the community to harness the collective knowledge and expertise of its members, resulting in comprehensive and up-to-date resources. We plan to calculate likelihood following the model we continued in 2021 to determine incidence rate instead of frequency to rate how likely a given app may contain at least one instance of a CWE. This means we aren’t looking for the frequency rate (number of findings) in an app, rather, we are looking for the number of applications that had one or more instances of a CWE. We can calculate the incidence rate based on the total number of applications tested in the dataset compared to how many applications each CWE was found in. Similarly to the Top Ten 2021, we plan to conduct a survey to identify up to two categories of the Top Ten that the community believes are important, but may not be reflected in the data yet.

CWE Data

The list explains the most dangerous web application security flaws and provides recommendations for dealing with them. F5 Distributed Cloud DDoS Mitigation defends against volumetric and application-specific layer 3-4 and advanced layer 7 attacks before they reach your network infrastructure and applications. However, rushing to get applications out the door can introduce a multitude of security vulnerabilities. Developers might sacrifice secure coding practices to meet deadlines, leaving sensitive user data, such as passwords, exposed and vulnerable to hacking.

Our Network

The 2017 risk Insecure Deserialization is now part of the 2021 Software and Data Integrity Failures category. The analysis of the data will be conducted with a careful distinction when the unverified data is part of the dataset that was analyzed. Businesses should also keep audit logs that enable them to track any suspicious changes, record anomalous activity, and track unauthorized access or account compromises. Watch how you can reduce your security risk and ensure timely compliance with government regulations.

Survey

The Open Web Application Security Project (OWASP) is a nonprofit organization dedicated to improving software security. The OWASP AI Exchange serves as an open-source collaborative effort to progress the development and sharing of global AI security standards, regulations, and knowledge. Originally formed as the Open Web Application Security Project and incorporated as a nonprofit charity in 2004, OWASP provides impartial advice on best practices and promotes the creation of open standards. The presence of a risk on the OWASP Top 10 list does not necessarily indicate its prevalence or severity in all web applications, and the Top Ten is not ranked in a specific order or by priority. The Google Summer of Code (GSoC) 2025 program has wrapped, and OWASP’s participation once again delivered meaningful improvements across the open-source security ecosystem.

Whether you’re looking to expand your skills or discover new solutions, you’ll find everything you need to stay ahead of the curve. In addition, we will be developing base CWSS scores for the top CWEs and include potential impact into the Top 10 weighting. Plan to leverage the OWASP Azure Cloud Infrastructure to collect, analyze, and store the data contributed. The OWASP Top 10 states that XXE attacks typically target vulnerable XML processors, vulnerable code, dependencies, and integrations.

OWASP Top 10 Application Security Risks

The OWASP operates on a core principle that makes all of its material freely available and accessible on its website. This open community approach ensures that anyone and any organization can improve their web application security. The materials it supplies include documentation, events, forums, projects, tools, and videos, such as the OWASP Top 10, the OWASP CLASP web protocol, and OWASP ZAP, an open-source web application scanner. Companies should adopt this document and start the process of ensuring that their web applications minimize these risks.
