A comprehensive guide and set of payloads for penetration testing web applications that process XML input. It details how to test for major vulnerabilities such as XXE, XPath injection, SSRF, and XML parsing attacks, providing step-by-step workflows and advanced payloads for identifying data exposure and security flaws.

This guide details methodologies for identifying and exploiting XML External Entity (XXE) injection vulnerabilities in web applications. It covers basic file retrieval, blind XXE detection using out-of-band techniques, and data exfiltration, all critical steps during authorized penetration testing of XML-consuming APIs and services.

This skill provides a comprehensive, structured methodology and checklist for identifying Remote Code Execution (RCE) vulnerabilities across various web applications. It covers advanced attack vectors such as OS command injection, Server-Side Template Injection (SSTI), insecure deserialization, file upload flaws, and XXE. Use this guide during web application penetration testing or bug bounty hunting to systematically discover arbitrary code execution paths.

This comprehensive checklist details how to test for XML External Entity (XXE) injection vulnerabilities. It covers classic, blind, error-based, and out-of-band techniques, enabling testers to identify weaknesses in XML parsers. The methodology includes finding various injection points (e.g., file uploads, SOAP/REST endpoints) and exploiting potential risks like file disclosure, SSRF, and DoS. Use this guide for robust web application security testing and bug bounty hunting.

This router serves as the main entry point for comprehensive injection testing. It helps security professionals classify dangerous input flows—such as XSS, SQLi, SSRF, XXE, etc.—by determining the final sink or interpreter (e.g., browser context, database, XML parser, shell). Use it when unsure which specific injection vector to prioritize.

A comprehensive, expert playbook for challenging insecure file upload mechanisms. It provides advanced attack vectors covering validation bypass (magic bytes, extension), storage path abuse (traversal, overwrite), and exploitation of post-upload processing chains (XXE, RCE, CMDi). Essential for deep security auditing of file-handling workflows.

A comprehensive playbook for testing XSLT injection vulnerabilities. This guide details advanced attack chains, starting with processor fingerprinting (Java, PHP, .NET, libxslt). It covers critical vectors including XXE (External Entities), Server-Side Request Forgery (SSRF) via document(), arbitrary file writing (EXSLT), and achieving Remote Code Execution (RCE) through language-specific extensions.

A comprehensive, expert-level playbook covering XML External Entity (XXE) vulnerabilities. This guide details advanced attack techniques across multiple contexts, including SOAP, REST, SVG, and Office files. Key topics covered include blind detection, out-of-band (OOB) data exfiltration, local file reading (e.g., /etc/passwd), and chaining XXE to achieve SSRF or RCE.
