GHSA-G7MP-V763-325C

Vulnerability from github – Published: 2026-10-05 09:31 – Updated: 2026-10-05 09:31

Details

The specific flaw exists within the Configuration → Services → Music on Hold functionality of the web portal listening on TCP port 443. The application is intended to allow users to upload WAV audio files but fails to properly validate the uploaded file type. An attacker can exploit this behavior to upload a malicious shared object (.so) instead of a WAV file. When the uploaded file is subsequently processed by the affected component, attacker-controlled code is loaded and executed in the context of the affected process. This can result in remote code execution and potentially full compromise of the underlying Linux system.

Severity

8.4 (High)

Title

Mitel MiVoice Office 400 Music on Hold WAV File Upload Code Execution

Summary

DigitalCanion SA has discovered a vulnerability that allows remote attackers to execute arbitrary code on affected installations of the product. Authentication may be required to exploit this vulnerability. The specific flaw exists within the Configuration → Services → Music on Hold functionality of the web portal listening on TCP port 443. The application is intended to allow users to upload WAV audio files but fails to properly validate the uploaded file type. An attacker can exploit this behavior to upload a malicious shared object (.so) instead of a WAV file. When the uploaded file is subsequently processed by the affected component, attacker-controlled code is loaded and executed in the context of the affected process. This can result in remote code execution and potentially full compromise of the underlying Linux system.
