Summary

Mitel MiVoice Office 400 from 11.0.96.0 has a path traversal flaw (CWE-31) in the Maintenance, System Logs function of its web management portal on TCP port 443. The application does not properly validate user-supplied file paths, so a manipulated path reaches files outside the system logs directory. A remote attacker with high privileges can download files, including potentially sensitive system and application files.
