Use modern archiving tools or libraries that automatically strip leading slashes and prevent ../ traversal. To make this write-up even more useful, could you tell me:

When a vulnerable service or application extracts this file using traditional methods (e.g., directly taking the filename from the zip entry without sanitization), the application will follow the ../ instructions and write shell.php to the web root rather than the intended extraction folder. 4. Reproduction Steps (Technical) the XXCa.ss.ieXX.zip file. XXCa.ss.ieXX.zip

Check that filename.contains("..") or use canonical paths to ensure the destination is safe. Use modern archiving tools or libraries that automatically
