Synopsis

The Microsoft Azure Connected Machine Agent installation on the remote host is affected by an elevation of privilege vulnerability.

Description

The Microsoft Azure Connected Machine Agent installation on the remote host is missing security updates. It is, therefore, affected by an elevation of privilege vulnerability (CVE-2026-21224).

- Successful exploitation of this vulnerability could allow a local attacker to gain SYSTEM privileges on the affected host by exploiting a flaw in how the agent handles service configuration or file permissions.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to Azure Connected Machine Agent version 1.60 or later
