This repository provides a proof-of-concept (POC) exploit for CVE-2021-41381, a directory traversal vulnerability in Payara Micro Community version 5.2021.6. The repository contains two files: a markdown README and a main exploit description file ('CVE: 2021-41381-POC'). The exploit demonstrates how an attacker can use a crafted HTTP request (with the --path-as-is curl option) to access sensitive configuration files on the server, specifically '/.//WEB-INF/classes/META-INF/microprofile-config.properties'. The exploit is executed by appending the traversal path to the base URL of a vulnerable Payara Micro instance and checking the response for specific configuration strings. The POC is operational for both Linux and Windows deployments of the target software. No weaponized or automated script is provided; the exploit is manual and intended for demonstration and verification purposes.
