System information disclosure via web-accessible phpinfo test
Published Dec 5, 2023 · Updated Oct 10, 2024
Information exposure in Microsoft Graph Core SDK for PHP before 2.0.2 allows remote attackers to read system details via HTTP. The published tests/GetPhpInfo.php script calls phpinfo() without restricting web execution, returning configuration, modules, and environment variables. Exploitation requires an application deployment that makes the Composer vendor directory web-accessible; the resulting disclosure can expose secrets used to access additional data.
