Attackers use these payloads in parameters, such as ?page= , ?file= , or ?image= , hoping the application will read and return the contents of the file, according to YesWeHack . Impact of Exposed AWS Credentials
The path you've mentioned seems to be URL-encoded and represents something like: /home/*/.aws/credentials .
@GetMapping("/file") public ResponseEntity<Resource> getFile(@RequestParam String path) Resource file = new FileSystemResource("/uploads/" + path); // missing validation -file-..-2F..-2F..-2F..-2Fhome-2F-2A-2F.aws-2Fcredentials
Protecting against path traversal—especially encoded variants—requires multiple layers.

Most academic papers follow a standard format often referred to as : A short summary of the entire paper. Introduction
Imagine a web application that allows users to view reports from a specific directory: https://example.com/show_report?report=2024-01-01.pdf Use "allow-lists" for file names and ensure that

-file-../../../home/*/.aws/credentials
Never trust user input. Use "allow-lists" for file names and ensure that any input containing ../ or encoded slashes is blocked or stripped. Most modern web frameworks provide built-in protection against path traversal. 2. Use IAM Roles (The "No Credentials" Rule)
