CVE-2017-7917
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 Cross-Site Request Forgery issue was discovered in Moxa OnCell G3110-HSPA Version 1.3 build 15082117 and previous versions, OnCell G3110-HSDPA Version 1.2 Build 09123015 and previous versions, OnCell G3150-HSDPA Version 1.4 Build 11051315 and previous versions, OnCell 5104-HSDPA, OnCell 5104-HSPA, and OnCell 5004-HSPA. The application does not sufficiently verify if a request was intentionally provided by the user who submitted the request, which could allow an attacker to modify the configuration of the device.
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 · high confidenceCross-Site Request Forgery (CSRF) vulnerability in Moxa OnCell device web management interfaces. The application fails to verify that requests originate from intentional user actions, allowing attackers to craft malicious requests that execute within an authenticated user's session to modify device configuration.

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 Moxa OnCell device modelAccess the device web management interface or check the device label/documentation to confirm the exact model number (G3110, G3150, 5104, or 5004)Affected if The device model is one of the OnCell series listed in affected products
-
Check the installed firmware versionLog into the web interface and navigate to the System Settings or Status page to view the firmware version, or use the device CLI if availableAffected if Firmware version is at or below 1.3 for G3110 Hspa, 1.2 for G3110 Hsdpa, 1.4 for G3150 Hsdpa, or any version for 5104/5004 models (since version limits are unspecified)
-
Confirm the web management interface is enabledVerify that the HTTP/HTTPS web interface is active and accessible on the device network settingsAffected if The web management interface is accessible and authentication sessions can be established
-
Inspect configuration forms for anti-CSRF protectionUse a browser developer tool or HTTP proxy to capture a configuration form submission (such as network settings, user management, or alarm settings) and examine whether the form includes a unique token parameter or checks Origin/Referrer headersAffected if The forms contain no anti-CSRF token parameter and the server does not validate Origin or Referrer headers on state-changing requests
A user is affected if they are running a vulnerable Moxa OnCell model within the specified firmware ranges with the web interface enabled and configuration forms lacking anti-CSRF token protection.

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 dataImplement anti-CSRF tokens on all state-changing forms, add Origin/Referrer header validation, and configure SameSite cookie attributes to prevent cross-origin request submission.
