Configuration disclosure via unsanitized service path
Published Jan 21, 2024 · Updated Oct 21, 2025
Path traversal in the DIR-859 1.06B01 HTTP POST handler allows remote attackers to read router configuration data without authentication. The fatlady.php handler uses the hedwig.cgi POST service value as a file path without validation, allowing ../ segments to escape the intended directory. A network-reachable management interface is sufficient, and returned configuration can expose administrator credentials and session data.
