This repository provides a proof-of-concept (PoC) exploit for CVE-2025-21385, an SSRF (Server-Side Request Forgery) vulnerability in Microsoft Purview. The main exploit is implemented as a Bash script (CVE-2025-21385.sh) that takes two arguments: a target URL (the SSRF callback destination) and a Purview URL (the vulnerable endpoint). The script constructs a JSON payload with the 'callback' parameter set to the target URL and sends it via HTTP POST to the Purview endpoint using curl. The response is saved and displayed if the exploit is successful. The repository also includes a README.md with detailed usage instructions, requirements, and example commands, as well as a standard GNU GPL v3 license file. No hardcoded endpoints are present in the script; all endpoints are provided by the user at runtime. The exploit is intended for educational and authorized penetration testing purposes only.
