CVE-2015-7938
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 · uneditedAdvantech EKI-132x devices with firmware before 2015-12-31 allow remote attackers to bypass authentication via unspecified vectors.
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 confidenceAuthentication bypass vulnerability in Advantech EKI-132x devices with firmware dated before December 31, 2015 allows remote attackers to bypass authentication mechanisms through unspecified vectors, granting unauthorized access to the 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 modelAccess the device web interface or check the physical device label for the model number. Confirm it is an Advantech EKI-1321 or EKI-1322 series device.Affected if The device model is EKI-1321 or EKI-1322
-
Locate firmware version informationLog into the device web interface and navigate to System > Firmware Information or System > Device Information. Record the firmware version and build date.Affected if Firmware version or date cannot be determined from the device interface
-
Compare firmware date to affected versionCheck the firmware build date shown in the device interface. Compare it to the affected date range of 2015-10-06 or earlier.Affected if Firmware build date is 2015-10-06 or earlier (before the 2015-12-31 patched release)
-
Verify network accessibilityDetermine if the device management interface (HTTP/HTTPS) is accessible from untrusted network segments or the public internet.Affected if The device web interface is exposed to untrusted networks without firewall protection
The device is affected if it is an EKI-1321 or EKI-1322 with firmware dated 2015-10-06 or earlier, and the management interface is network-accessible.

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 · scopedUpdate firmware to the version released on or after 2015-12-31; if no update is available, isolate affected devices on a restricted network segment and monitor for unauthorized access attempts.
Any Advantech EKI-1321/1322 firmware release dated 2015-12-31 or later
- 1. Identify the current firmware version installed on the EKI-1321 or EKI-1322 device
- 2. Navigate to the Advantech support website or contact Advantech directly to obtain the latest firmware version
- 3. Download the firmware version dated 2015-12-31 or later (these versions contain the authentication bypass fix)
- 4. Follow Advantech's official firmware upgrade procedure for the EKI-132x series devices
- 5. After upgrading, verify the device is functioning correctly and the new firmware version is applied
