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.

Title
Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution
Summary
DigitalCanion has discovered a vulnerability that allows an attacker to cause the system to load an attacker-controlled .so file instead of the expected legitimate module. The loading mechanism relies on a predictable module name without adequately verifying the file’s origin or integrity. A malicious shared object using the expected name can therefore be loaded by a privileged process. The module code then executes within the context and privileges of that process. This results in arbitrary code execution and full compromise of the Mitel Linux virtual machine.

Title
Mitel MiVoice Office 400 stored Cross-Site Scripting
Summary
DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content, resulting in a denial-of-service condition within the web application.
The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Users → Users List. The vulnerability occurs in the “Microsoft Exchange mailbox” field, which fails to properly validate or sanitize user-supplied input before storing and rendering it.
By injecting malicious JavaScript into this field, an attacker can cause the payload to execute whenever the affected user properties are accessed. This can prevent access to the affected user properties and result in a denial-of-service condition within the application's user-management functionality.

Title
Mitel MiVoice Office 400 stored Cross-Site Scripting
Summary
DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content into the web application.
The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Domains, specifically in the “Description” field. The application fails to properly validate or sanitize user-supplied input before storing and subsequently rendering the field.
By injecting malicious JavaScript into the Description field, an attacker can modify the content and behavior of the affected page when it is viewed by other users. This could allow an attacker to alter the page's appearance, display attacker-controlled content, or construct convincing phishing scenarios within the application's trusted web context.

Title
Mitel MiVoice Office 400 Backup Restoration Arbitrary File Write Leading to Root Code Execution
Summary
DigitalCanion has discovered a vulnerability in the backup restoration functionality that allows an attacker with access to the configured backup repository to introduce arbitrary files into the system during restoration.
The specific flaw exists within the backup restoration mechanism, which fails to properly validate the paths, file types, integrity, and authenticity of files contained within a restored TGZ archive. The application does not perform file-signature verification before extracting the archive, allowing a specially crafted backup to contain attacker-controlled files.
An attacker with access to the backup SFTP or other configured repository can therefore provide a malicious TGZ archive that, when restored by the system, may place arbitrary files on the underlying Linux system. Depending on the location and permissions of the extracted files, this behavior can potentially be leveraged to achieve arbitrary code execution with root privileges and compromise the underlying virtual machine.
The absence of enforced backup passwords further reduces the protection provided by the backup mechanism and may facilitate unauthorized access to the repository.

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.

Title
Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution
Summary
DigitalCanion has discovered a vulnerability that allows an attacker to cause the system to load an attacker-controlled .so file instead of the expected legitimate module. The loading mechanism relies on a predictable module name without adequately verifying the file’s origin or integrity. A malicious shared object using the expected name can therefore be loaded by a privileged process. The module code then executes within the context and privileges of that process. This results in arbitrary code execution and full compromise of the Mitel Linux virtual machine.

Title
Mitel MiVoice Office 400 stored Cross-Site Scripting
Summary
DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content, resulting in a denial-of-service condition within the web application.
The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Users → Users List. The vulnerability occurs in the “Microsoft Exchange mailbox” field, which fails to properly validate or sanitize user-supplied input before storing and rendering it.
By injecting malicious JavaScript into this field, an attacker can cause the payload to execute whenever the affected user properties are accessed. This can prevent access to the affected user properties and result in a denial-of-service condition within the application's user-management functionality.

Summary
DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content into the web application.
The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Domains, specifically in the “Description” field. The application fails to properly validate or sanitize user-supplied input before storing and subsequently rendering the field.
By injecting malicious JavaScript into the Description field, an attacker can modify the content and behavior of the affected page when it is viewed by other users. This could allow an attacker to alter the page's appearance, display attacker-controlled content, or construct convincing phishing scenarios within the application's trusted web context.

Title
Mitel MiVoice Office 400 Backup Restoration Arbitrary File Write Leading to Root Code Execution
Summary
DigitalCanion has discovered a vulnerability in the backup restoration functionality that allows an attacker with access to the configured backup repository to introduce arbitrary files into the system during restoration.
The specific flaw exists within the backup restoration mechanism, which fails to properly validate the paths, file types, integrity, and authenticity of files contained within a restored TGZ archive. The application does not perform file-signature verification before extracting the archive, allowing a specially crafted backup to contain attacker-controlled files.
An attacker with access to the backup SFTP or other configured repository can therefore provide a malicious TGZ archive that, when restored by the system, may place arbitrary files on the underlying Linux system. Depending on the location and permissions of the extracted files, this behavior can potentially be leveraged to achieve arbitrary code execution with root privileges and compromise the underlying virtual machine.
The absence of enforced backup passwords further reduces the protection provided by the backup mechanism and may facilitate unauthorized access to the repository.
