CVE-2026-5416

Managed Ethernet · Managed Ethernet Switch

A command injection vulnerability in Managed Ethernet Switches allows low-privileged attackers to achieve full system compromise.

Executive summary

A high-severity command injection vulnerability in Managed Ethernet Switches enables remote attackers to achieve full system compromise via an unneutralized name parameter.

Vulnerability

The vulnerability is caused by improper neutralization of special elements within a name parameter. A remote attacker with low-privileged access can inject arbitrary commands, resulting in full system compromise of the switch.

Business impact

With a CVSS score of 8.8, this vulnerability is extremely dangerous as it allows for complete control over network infrastructure hardware. An attacker could potentially intercept traffic, modify network configurations, or use the device as a persistent foothold within the internal network, causing significant operational and security damage.

Remediation

Immediate Action: Apply the vendor-provided firmware update immediately to all affected switches.

Proactive Monitoring: Monitor device logs for command execution attempts and unusual management traffic directed at the switch.

Compensating Controls: Restrict management interface access to dedicated, isolated management networks and disable unnecessary services on the switch.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Compromise of network infrastructure is a high-impact event that can facilitate further lateral movement across an organization. Administrators must prioritize the patching of all Managed Ethernet Switches and ensure that administrative interfaces are not exposed to untrusted segments of the network.
