Summary

A vulnerability in EduSoho prior to version 22.4.7 allows an unauthenticated remote attacker to read arbitrary files from the server by manipulating the fileNames[] parameter in the classroom-course-statistics export functionality. The attacker can use path traversal sequences to access configuration files like config/parameters.yml, which may contain secrets and database credentials.

Risk Assessment

The risk involves potential exposure of sensitive configuration data, including passwords and keys, which could lead to further system compromise and database access.

Recommendation

Immediately upgrade EduSoho to version 22.4.7 or later, which includes a fix for the arbitrary file read vulnerability.
