OWASP Top 10 Security Concerns In 2021

This page details the OWASP Top 10 security risks for 2021 as they pertain to the ZK framework. For risks that continue from 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

See OWASP Top 10 Security Concerns In 2017#A05 - Broken Access Control

A02:2021 - Cryptographic Failures

See OWASP Top 10 Security Concerns In 2017#A03 - Sensitive Data Exposure

A03:2021 - Injection

• OWASP Top 10 Security Concerns In 2017#A07 - Cross-Site Scripting (XSS)

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: ZK 10.0.0 has refined how GET and POST requests are processed to prevent HTTP verb tampering attacks.
• Enhanced Security Framework: Includes Synk Scanning, CodeQL PR Scanning, and SonarCube to analyze and protect the codebase.
• Enable InaccessibleWidgetBlockService by Default: Blocks requests from inaccessible widgets enhancing security by preventing interactions with UI components that should not be accessible.

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.

A06:2021 - Vulnerable and Outdated Components

A07:2021 - Identification and Authentication Failures

See OWASP Top 10 Security Concerns In 2017#A02 - Broken Authentication

A08:2021 - Software and Data Integrity Failures

See OWASP Top 10 Security Concerns In 2017#A08 - Insecure Deserialization

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.
