Custom Scripts
Overview
Custom Scripts is a web application security tool that appears across web application security workflows in this knowledge base. It is referenced as part of higher-level security analysis, investigation, monitoring, or validation activity rather than as an end in itself.
What It Is
Custom Scripts is best understood as a web-application-security tool in this knowledge base. Its role is conceptual and system-facing rather than procedural: it gives analysts or defenders a structured way to examine evidence, model system behavior, or reason about security state.
How It Works
Custom Scripts works by turning technical inputs into more interpretable outputs at the system level. Across the source skills, it appears as part of larger analysis, investigation, monitoring, or validation loops rather than as a standalone end state.
Core Concepts
- penetration testing
- business logic
- owasp
- web security
- burpsuite
- manual testing
- web application security
Typical Workflow
- Document all critical business processes and their expected constraints.
Use Cases
- During authorized penetration tests when automated scanners have found few technical vulnerabilities
- When assessing e-commerce platforms for pricing, cart, and payment flow manipulations
- For testing multi-step workflows (registration, checkout, approval processes) for bypass opportunities
- When evaluating rate-limited features like vouchers, coupons, referrals, and rewards systems
- During security assessments of financial applications, voting systems, or any application with critical business rules
Limitations
- Output still depends on context, data quality, and surrounding analysis.
- The tool should be interpreted as part of a broader workflow, not as a complete answer by itself.
- Capabilities and visibility vary depending on environment, integrations, and available inputs.
