CVE-2024-30220
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCommand injection vulnerability in PLANEX COMMUNICATIONS wireless LAN routers allows a network-adjacent unauthenticated attacker to execute an arbitrary command by sending a specially crafted request to a certain port. Note that MZK-MF300N is no longer supported, therefore the update for this product is not provided.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · low confidenceCommand injection vulnerability in PLANEX COMMUNICATIONS wireless LAN routers allows a network-adjacent unauthenticated attacker to execute arbitrary commands by sending specially crafted requests to a specific port. The vulnerability has a CVSS score of 8.8 (HIGH), indicating significant risk.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelCheck the device label or web interface for the exact model name (MZK-MF300N or MZK-MF300HP2)Affected if Model is MZK-MF300N (all versions) or MZK-MF300HP2 (version 1.18 or lower)
-
Determine the firmware versionAccess the router admin web interface (typically at 192.168.1.1) and check the firmware version under System or Status settings, or use the command: curl -s http://192.168.1.1/ | grep -i firmwareAffected if Firmware version cannot be determined, is unknown, or for MZK-MF300HP2 is 1.18 or lower
-
Locate the admin web interfaceAttempt to access the router web interface on the local network (commonly ports 80 or 8080)Affected if The admin interface is accessible from an untrusted network segment
-
Check for the vulnerable service portScan the router from the LAN side using: nmap -p <port> 192.168.1.1 (or the router's actual IP) - the specific port number should be determined from the product documentation or by identifying the service running on common portsAffected if The service port that handles the vulnerable request is exposed and accessible from the network
-
Verify network accessibilityConfirm whether the router management interface and vulnerable port are reachable from network segments that contain untrusted devices (guest networks, IoT networks, or external networks if port forwarding is configured)Affected if The router or its management services are reachable from untrusted network segments without firewall filtering
The environment is affected if a Planex MZK-MF300N (any firmware) or MZK-MF300HP2 (firmware <= 1.18) router is deployed and its management interface or vulnerable service port is accessible from a network segment that could contain untrusted attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataIsolate affected routers from untrusted networks using firewall rules and VLAN segmentation; for EOL devices like MZK-MF300N where no patch is available, replace with actively supported hardware.
