AI-suggested

To mitigate CVE-2026-32291, organizations should immediately update GL-iNet Comet KVM devices to firmware version 1.8.2 or later, where authentication on the UART console is enforced. If updating firmware is not immediately possible, physical security controls must be strengthened to prevent unauthorized access to the devices, including securing device enclosures, restricting access to server rooms, and monitoring for tampering. Additionally, organizations should audit their deployment environments to identify any devices at risk of physical compromise. Implementing tamper-evident seals and intrusion detection mechanisms can provide early warning of physical access attempts. Network segmentation should be employed to limit the impact of any compromised KVM device. Finally, organizations should consider disabling or physically blocking UART interfaces if they are not required for normal operations, reducing the attack surface. Regular security training for personnel on the risks of physical device access is also recommended.

Description

The GL-iNet Comet (GL-RM1) KVM before 1.8.2 does not require authentication on the UART serial console. This attack requires physically opening the device and connecting to the UART pins.
