Remote Code Execution in DigitalCanion Configuration Portal

Publication date: 2026-10-05

Last updated on: 2026-10-05

Assigner: Switzerland Government Common Vulnerability Program

Description
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.

Executive Summary

This vulnerability allows remote attackers to execute arbitrary code on affected installations. The flaw exists in the Music on Hold feature of a web portal running on TCP port 443. The application fails to validate uploaded files properly, letting attackers upload malicious shared object files (.so) instead of WAV files. When processed, this executes attacker-controlled code in the system context, potentially leading to full system compromise.

Detection Guidance

Check for unauthorized uploads to the Music on Hold service on TCP port 443. Inspect WAV file uploads for unexpected file types like .so files. Monitor for suspicious processes loading shared objects from the upload directory.

Impact Analysis

An attacker could exploit this to run arbitrary code on your system, potentially gaining full control over the affected Linux system. This could lead to data theft, system damage, or further network compromise if the system is connected to other networks.

Mitigation Strategies

Disable the Music on Hold upload feature if not needed. Implement strict file type validation to only allow WAV files. Restrict write permissions to the upload directory. Update the application to patch the file validation flaw.
