CVE-2026-12197

Ruijie · EG105G-P

A security flaw has been discovered in the Ruijie EG105G-P network gateway, potentially compromising device security.

Executive summary

A critical security flaw in the Ruijie EG105G-P network gateway exposes the device to potential unauthorized access or control.

Vulnerability

This flaw affects the Ruijie EG105G-P gateway. Given the nature of network hardware vulnerabilities, it is likely that this issue could be exploited by remote, unauthenticated attackers to gain unauthorized control over the gateway device.

Business impact

The CVSS score of 7.2 indicates a high-severity risk. A compromised gateway can serve as a pivot point for attackers to intercept network traffic, launch man-in-the-middle attacks, or gain unauthorized access to the internal network, causing significant reputational and operational damage.

Remediation

Immediate Action: Check the Ruijie support website for firmware updates and apply them to all affected EG105G-P units.

Proactive Monitoring: Monitor network traffic for unusual outbound connections or attempts to access the management interface from unauthorized subnets.

Compensating Controls: Restrict access to the device management interface to trusted internal IP addresses and disable unnecessary management services.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Urgent action is required to patch this network gateway. Failure to secure the perimeter device could lead to a full compromise of the internal network infrastructure. Ensure all management consoles are isolated from public access.
