CVE-2026-104809: Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution
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.

What capability does an attacker need to exploit this issue?
The attacker must be able to place or cause the system to load a malicious shared object file with the predictable name expected by the vulnerable loading mechanism. The available information does not specify how an attacker would obtain that ability.
