## Overview

DigitalCanion has discovered a path traversal vulnerability that allows an attacker to access files outside of the intended directory.




The specific flaw exists within the Maintenance → System Logs functionality of the web management portal listening on TCP port 443. The application fails to properly validate user-supplied file paths, allowing an attacker to manipulate the requested path and traverse the underlying directory structure.




By exploiting this vulnerability, an attacker can access and download files located outside the intended system logs directory, including potentially sensitive system and application files.
