OWASP TOP 10: Application logic vulnerabilities 2025

🎉 Welcome to the Complete OWASP TOP 10 Course on Application Logic Vulnerabilities! 🚀

Understanding Application Logic Vulnerabilities: Application logic vulnerabilities are a weakness in an application's design or code that allows an attacker to manipulate its functionality to achieve unauthorized outcomes. These flaws often go undetected because they do not necessarily involve code-level errors but rather a misconfiguration of the app's workflow. 🛡️

OWASP Top 10 and Beyond: The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about what the most critical internet application security flaws are, based on hundreds of aforementioned applications from around the world, and is designed to help developers create a secure application by considering these represented risks early in the development lifecycle. 🌍

What Are Application Logic Vulnerabilities? At their core, application logic vulnerabilities arise when an application doesn't act as expected due to faulty logic or improper workflow. An attacker can exploit this by manipulating input or navigation in ways the application's designer did not anticipate, often without needing specialized tools, simply by modifying a URL or HTML code. 🌐

Are "Application Logic Vulnerabilities," "Logic Flaws," and "Business Logic" the Same? Yes! These terms are often used interchangeably to refer to a vulnerability that occurs when an application's logic can be bypassed or manipulated in an unintended way, impacting business operations. 🤝

Why Learn About Application Logic Vulnerabilities? Understanding and preventing these vulnerabilities is crucial because they can lead to a wide range of impacts on a web application. From minor inconveniences to major security breaches leading to data theft or financial loss, the potential risks are significant. By learning about them, you can safeguard your applications against such vulnerabilities. 🔒

Common Types of Broken Application Logic Vulnerabilities:

1. 🛡️ Authentication Flags and Privilege Escalations: Exploiting weak authentication mechanisms or escalating privileges beyond intended levels.
2. 💰 Critical Parameter Manipulation: Altering critical parameters to gain unauthorized access to information or functions.
3. 🍪 Developer's Cookie Tampering: Modifying cookies to bypass security checks or access restricted areas.
4. 📁 LDAP Parameter Identification: Gaining access to the Lightweight Directory Access Protocol (LDAP) without authorization.
5. ⚖️ Business Constraint Exploitation: Circumventing business rules for financial gain or data extraction.
6. 🚫 Business Flow Bypass: Skipping necessary steps in a workflow to achieve objectives like altering account settings or bypassing payments.
7. 🤖 Client-Side Business Routines: Exploiting JavaScript, Flash, or Silverlight routines embedded on the client side.
8. ℹ️ Identity or Profile Extraction: Gaining access to user profiles or sensitive information.
9. 📄 File or Unauthorized URL Access: Accessing restricted files or URLs that contain business logic or sensitive data.

Preventing Application Logic Vulnerabilities:

1. 🔍 Review Methodology: Employ comprehensive methodologies like OWASP's Code Review guide to identify and fix security issues during the development lifecycle.
2. 🛡️ Defensive Strategies: Implement defensive programming techniques that anticipate attacks on application logic.
3. 🔎 Existing Vulnerability Scanners: Use automated scanning tools to detect vulnerabilities in your applications.
4. ⚙️ TestBed Applications: Create and test applications in a controlled environment to understand how they might be exploited.
