Understanding the Limitations of Static Analysis Tools
Have you ever wondered why some vulnerabilities slip through static analysis tools? While they effectively catch issues like SQL injection and XSS, they’re often blind to critical vulnerabilities such as authentication bypass and privilege escalation.
Key Insights:
- Architectural Constraints: Most Static Application Security Testing (SAST) tools rely on Abstract Syntax Trees (ASTs), which capture code structure but lack the semantic depth necessary for thorough security analysis.
- Business Logic Vulnerabilities: Unlike injection flaws, these vulnerabilities often arise from missing checks and poor interactions between code components. ASTs cannot identify these subtle issues in isolation.
- Role of Taint Analysis: Traditional taint analysis focuses on data flow but overlooks vital logic checks, leading to undetected vulnerabilities.
Moving Forward:
To succeed against modern threats, we need tools that build complete semantic indices and trace call chains across services. Gecko’s scanner utilizes advanced semantic indexing to find multi-step vulnerabilities previously missed by standard tools.
