Microsoft Open Management Infrastructure < 1.6.8.1 Multiple Vulnerabilities

critical Nessus Plugin ID 153474

Language:

Synopsis

The remote Azure Open Management Infrastructure server is affected by multiple vulnerabilities

Description

The version of Azure Open Management Intfrastructure installed on the remote host is prior to 1.6.8.1. It is, therefore, affected by multiple vulnerabilities:

 - A remote code execution vulnerability exists in the OMI agent. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands with root privileges. (CVE-2021-38647)
- Multiple privilege escalation vulnerabilities exists in the OMI agent. An unauthenticated, remote attacker can exploit this, to gain priviledged access to the system. (CVE-2021-38645, CVE-2021-38648, CVE-2021-38649)

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

Solution

Upgrade to Azure Open Management Infrastructure version 1.6.8.1 or later.
