CVE-2024-50375
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 · uneditedA CWE-306 "Missing Authentication for Critical Function" was discovered affecting the following devices manufactured by Advantech: EKI-6333AC-2G (<= 1.6.3), EKI-6333AC-2GD (<= v1.6.3) and EKI-6333AC-1GPO (<= v1.2.1). The vulnerability can be exploited by remote unauthenticated users capable of interacting with the default "edgserver" service enabled on the access point.
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 confidenceThe Advantech EKI-6333AC series wireless access points contain a missing authentication vulnerability in the 'edgserver' service. Remote unauthenticated attackers can exploit this critical flaw (CVSS 9.8) to interact with the service without credentials, potentially gaining full administrative control over the affected device.

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 device modelLog into the device web interface or check the device label to confirm it is an Advantech EKI-6333AC series access point (specifically 2G, 2GD, or 1GPO variants)Affected if The device is an EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO model
-
Check installed firmware versionAccess the device admin interface or use SNMP to retrieve the current firmware versionAffected if Firmware version is below 1.6.5 for 2G/2GD models, or below 1.2.2 for 1GPO model
-
Verify edgserver service statusCheck if the 'edgserver' service is running on the device via CLI (ps aux | grep edgserver) or through the device management interfaceAffected if The edgserver process is running and exposed on the network
-
Assess network exposureScan the network to determine if the edgserver port (typically ports 8080, 8443, or vendor-specific) is accessible from untrusted networks or the internetAffected if The edgserver service port is reachable from outside the trusted network without authentication requirements
A user is affected if they have an EKI-6333AC-2G/2GD device on firmware below 1.6.5 or an EKI-6333AC-1GPO device below 1.2.2, with the edgserver service running and network-accessible without credentials.

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.
dbcve · scoped1.2.21.6.5
Implement authentication on the edgserver service or apply vendor-supplied patches/firmware updates; if no patch is available, disable the edgserver service and isolate the device behind a firewall to reduce attack surface.
EKI-6333AC-2G and EKI-6333AC-2GD: upgrade to firmware version 1.6.5 or later; EKI-6333AC-1GPO: upgrade to firmware version 1.2.2 or later
- Identify the exact model of the Advantech EKI device (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO) in your environment
- Download the firmware update from the official Advantech support website or contact Advantech directly for the patched firmware
- Verify the firmware hash/checksum if provided by Advantech to ensure integrity
- Follow Advantech's official firmware upgrade procedure for the specific device model - typically involves uploading the firmware file through the web interface or using TFTP/FTP
- Ensure the upgrade is performed during a planned maintenance window as firmware updates may cause brief network interruption
- After upgrading, verify the device is operational and the edgserver service is running properly
- Confirm the new firmware version matches the fixed release (1.6.5 for 2G/2GD models, 1.2.2 for 1GPO model)
