Executive Summary

This is a path traversal vulnerability in koozali's SME Server version 11.0rc1-215. An unauthenticated attacker can exploit the View Logs functionality to access files outside the intended directory. This could allow them to exfiltrate sensitive system and application files located outside the logs directory.
