OWASP Top 10 Security Concerns In 2021

The Open Web Application Security Project (OWASP) is a global nonprofit organization dedicated to enhancing software security. Its OWASP Top 10 list serves as a crucial tool in raising awareness about web application security, highlighting the ten most significant risks.

This page details the OWASP Top 10 security risks for 2021 as they pertain to the ZK framework and offer insights into how developers can proactively address these threats. For risks that have been listed in the 2017 list, links are provided to the original explanations, with updates and new risks detailed directly on this page.

A01:2021 - Broken Access Control

ZK Framework has strengthened its access control measures by enabling the InaccessibleWidgetBlockService by default since 10.0.0. This service enhances security by automatically blocking interactions with UI components that are not meant to be accessible, such as disabled or hidden components. This default setting helps prevent unauthorized access and ensures that access control policies are enforced consistently across the application.

A03:2021 - Injection

A04:2021 - Insecure Design

ZK 10.0.0 addresses insecure design through several security enhancements, reinforcing the framework's defense against potential threats:

  • Stricter GET/POST Handling: To prevent HTTP verb tampering attacks, ZK 10.0.0 has refined how GET and POST requests are processed. It now returns a 404 error if an Asynchronous Update (AU) request is incorrectly sent via GET, ensuring proper usage of HTTP methods.
  • Proactive Security Measures in CI/CD Process: ZK 10.0.0 integrates three advanced security checks into our CI/CD process:
    • Synk Scanning: This tool analyzes both source code and third-party dependencies for vulnerabilities.
    • CodeQL PR Scanning: It assesses pull requests for Java, JavaScript, and TypeScript to find security flaws before they are merged.
    • SonarCube: It scans the source code comprehensively to identify bugs, vulnerabilities, and security risks.

A05:2021 - Security Misconfiguration

ZK Framework has enhanced its security measures to further protect against XML External Entities (XXE) attacks. As of ZK 10.0.0, the XML parsing configuration has been updated to disallow Doctype declarations, which are a common vector for XXE attacks. This change prevents the XML parser from processing XML documents that include external entities, thereby mitigating potential security risks. For further details, see ZK-5622 Disallow Doctype on parsed XML files in ZK to increase security.

ZK Framework has taken steps to enhance security configurations to prevent common misconfigurations that could lead to security vulnerabilities. A significant enhancement, implemented as of ZK 9.5.0, is the splitting of the DHtmlUpdateServlet into two dedicated servlets: one for handling dynamic AJAX updates (AU Servlet) and another for serving static resources (Resource Servlet). This separation enhances security by reducing the risk of misconfigurations that could expose sensitive data or functionality unintentionally.

A06:2021 - Vulnerable and Outdated Components

ZK has taken proactive steps to address the risks associated with using vulnerable and outdated components. As of ZK 9.5.0, the framework has integrated the OWASP Dependency Check into its build process. This tool helps identify and mitigate security vulnerabilities in third-party libraries and dependencies by scanning them against known vulnerability databases. This measure significantly enhances security by ensuring that potential vulnerabilities are identified and addressed promptly before production deployment.

A08:2021 - Software and Data Integrity Failures

A09:2021 - Security Logging and Monitoring Failures

See OWASP Top 10 Security Concerns In 2017#A10 - Insufficient Logging & Monitoring

A10:2021 - Server-Side Request Forgery (SSRF)

While ZK Framework itself does not provide specific mechanisms for making server-side requests, app developers need to ensure the safe handling of URLs and external resources, employing strict input validation and allowing accessible internal systems.

Summary

Developers should understand that while a front-end framework like ZK plays a vital role in user interface development, it represents only a fraction of the entire application system. It's important to recognize that vulnerabilities within the UI layer are not the primary source of weaknesses that require fortification. Instead, developers must comprehensively assess all layers of their applications to identify potential vulnerabilities that attackers could exploit. With this holistic understanding, software developers can implement proactive measures across the entire system to mitigate these threats effectively.
