Arbitrary file read via export path traversal
Published Jan 22, 2026 · Updated Jan 22, 2026
Path traversal in EduSoho before 22.4.7 allows remote attackers to read arbitrary server files through an export request. The classroom-course-statistics export handler passes each fileNames[] value to filesystem access without confining the resolved path to an export directory. No authentication is required, and traversal sequences can expose configuration secrets and database credentials stored on the server.
