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 · moderate confidence

Unauthenticated OS command injection in PROSCEND and ADVICE industrial cellular routers (models M330-w through ICR 111WG) allows remote attackers to execute arbitrary operating system commands without any authentication, likely via insecure input handling in web management interfaces.

MitigationIsolate affected routers behind firewalls with strict ACLs limiting management access to trusted IPs, apply vendor firmware updates when available, and disable unauthenticated management interfaces exposed to the internet.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model
    Access the router web interface or check physical device label to confirm the exact model (M330 W, M330 W5, M350 5g, M350 W5g, M350 6, M350 W6, M301 G, M301 Gw, or ICR 111WG)
    Affected if Model matches Proscend M330-w through ICR 111WG product line
  2. Check installed firmware version
    Log into the router web management interface and navigate to System Status or Firmware Info page to view the current firmware version. Compare against affected versions: M330 W/W5 < 1.11, M350 5g/W5g/6/W6 < 1.02, M301 G/Gw < 2.20
    Affected if Firmware version is lower than the affected version for your model
  3. Verify web management interface accessibility
    Confirm whether the router web management interface (HTTP/HTTPS on ports 80/443 or custom ports) is accessible from the network. Check router firewall settings and port forwarding rules
    Affected if Web management interface is accessible from untrusted networks (internet or guest VLANs)
  4. Check remote management settings
    In the router web interface, examine the Administration or Remote Access settings to determine if remote management via web interface is enabled and from which IP sources
    Affected if Remote web management is enabled and permits access from non-trusted IP addresses

Device is affected if it is a Proscend M330-w through ICR 111WG router running firmware below the specified version AND its web management interface is accessible from untrusted networks.

Upgrade available Upgrade to 1.02 / 1.11 / 2.20 or later
Fixed in 1.021.112.20
Interim mitigation

Isolate affected routers behind firewalls with strict ACLs limiting management access to trusted IPs, apply vendor firmware updates when available, and disable unauthenticated management interfaces exposed to the internet.

Recommended fix Moderate confidence

Firmware 1.11 for M330-W/M330-W5; Firmware 1.02 for M350 series; Firmware 2.20 for M301-G/GW (or latest available from PROSCEND)

  1. 1. Identify the exact model number of the PROSCEND device (M330-W, M330-W5, M350-5G, M350-W5G, M350-6, M350-W6, M301-G, or M301-GW)
  2. 2. Check the current firmware version by accessing the device's web interface or administrative console
  3. 3. Navigate to the PROSCEND official support page or contact PROSCEND technical support to obtain the latest firmware
  4. 4. Download the firmware version 1.11 or later for M330-W/M330-W5 devices
  5. 5. Download the firmware version 1.02 or later for M350-5G/M350-W5G/M350-6/M350-W6 devices
  6. 6. Download the firmware version 2.20 or later for M301-G/M301-GW devices
  7. 7. Follow the manufacturer's firmware upgrade procedure, typically found in the device administration manual
  8. 8. After upgrading, verify the firmware version has been successfully applied
