Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of open-vm-tools installed on the remote host is prior to 12.3.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2329 advisory.

VMware Tools contains a SAML token signature bypass vulnerability. A malicious actor that has been granted Guest Operation Privileges https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere- security/GUID-6A952214-0E5E-4CCF-9D2A-90948FF643EC.html in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias https://vdc-download.vmware.com/vmwb-repository/dcr-public/d1902b0e-d479-46bf-8ac9-cee0e31e8ec0/07ce8dbd- db48-4261-9b8f-c6d3ad8ba472/vim.vm.guest.AliasManager.html . (CVE-2023-34058)

open-vm-tools contains a file descriptor hijack vulnerability in the vmware-user-suid-wrapper. A malicious actor with non-root privileges may be able to hijack the /dev/uinput file descriptor allowing them to simulate user inputs. (CVE-2023-34059)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update open-vm-tools' to update your system.
