Lambda-Proxy is a specialized testing utility that enables security professionals to assess AWS Lambda functions for SQL injection vulnerabilities. The tool functions by creating a bridge between SQLMap's HTTP-based attack methodology and AWS Lambda's invoke mechanism through a local HTTP proxy server. The utility transforms traditional HTTP requests into AWS Lambda function calls, allowing penetration testers to leverage SQLMap's comprehensive SQL injection detection capabilities against serverless functions. Users configure the tool by updating a request.txt file with their target Lambda function's event data structure. Lambda-Proxy addresses the challenge of testing serverless architectures where traditional web application security testing tools may not directly apply. By converting HTTP-based attacks to Lambda invoke calls, it enables the use of established SQL injection testing methodologies in cloud-native environments. The tool requires proper AWS credentials and permissions to invoke the target Lambda functions during testing. It serves as an adapter layer that makes serverless function security testing more accessible using familiar tools and techniques.
