Summary

A vulnerability was found in DigitalCanion SA's product within the Configuration → Services → Music on Hold functionality of the web portal on TCP port 443, which fails to properly validate uploaded file types. An authenticated attacker can upload a malicious .so file instead of a WAV file, leading to remote code execution in the context of the affected process.

Risk Assessment

Remote code execution and full compromise of the underlying Linux system are possible. Authentication is required, but the impact can be critical for the entire infrastructure.

Recommendation

Immediately update the product to a version that fixes the file upload validation. Restrict portal access to trusted networks and verify that no unauthorized .so files were uploaded.

Original NVD description (English source)

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.
