CRITICAL 9.8

DescriptionCVE.org

An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Failure to validate the value of usbPartitionName, which is directly used in doSystemCmd, may lead to critical command injection vulnerabilities.

Executive ViewAI

Why It Matters

Tenda W20E routers running firmware V4.0br_V15.11.0.6 contain a critical remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands. Organizations using this device model face immediate risk of complete network compromise, data exfiltration, and lateral movement into connected systems.

Business Impact: Severe

Compensating Controls

Implement network segmentation to isolate affected routers from critical systems; restrict administrative access to the device via network ACLs; disable the USB partition feature if not in use; monitor WAN traffic for suspicious command patterns; implement intrusion detection signatures targeting CVE-2026-24107 command injection attempts; consider WAF rules if the device is internet-facing; maintain offline backups of critical configurations.
