Step 5: Modify the request. This technique to hijack a service worker enables three key outcomes: HTML filter evasion; Bypassing CSP; Escalating XSS; The importScripts() function lies at the heart of this vulnerability - it allows a SW to retrieve JavaScript from a different domain. You may need to disable this setting if it is preventing the site from working correctly. The client processes the function's DOM-based JSON injection arises when a script incorporates controllable data into a string that is parsed as a JSON data structure and then processed by the application. Penetration testing Accelerate To prevent session hijacking using the session id, you can store a hashed string inside the session object, made using a combination of two attributes, remote addr and remote port, that can be accessed at the web server inside the request object. Many applications use JWTs to implement custom security mechanisms.
