variant-analysis

Variant analysis helps find similar vulnerabilities by leveraging pattern-based searching and abstraction techniques. You systematically search the codebase for code patterns mirroring a known vulnerability to prevent the recurrence of the same root cause.

Semgrep query building is assisted by iteratively generalizing code patterns from a known vulnerability snippet. This abstraction technique refines the search rules to accurately match related bugs across the entire codebase.

Systematic variant hunting automates vulnerability discovery by tracing user input paths to dangerous functions. Using tools like ripgrep, you search the entire codebase for instances lacking proper sanitization, mirroring the initial SQL injection root cause.

Yes, CodeQL is fully supported for variant analysis on web applications. The Skill assists in creating and refining CodeQL queries to systematically discover similar vulnerabilities and build automated code analysis rules.

Variant analysis relies on an initially identified issue or code snippet to function effectively. The process requires a known vulnerability pattern to generalize from, preventing the recurrence of that specific root cause across the codebase.

Ripgrep and Semgrep are utilized for iterative pattern generalization and code auditing. These tools enable systematic variant analysis to discover similar vulnerabilities and build automated code analysis rules.
