CVE-2014-8331
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.

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 confidenceMultiple CSRF vulnerabilities in Huawei HiLink E3236 and E3276 mobile broadband modems allow remote attackers to hijack administrator authentication by tricking logged-in admins into visiting malicious pages. The vulnerabilities enable attackers to change configuration settings or invoke device functions without the administrator's consent.

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 device modelLog into the Huawei HiLink web interface and check the device information page, or inspect the device label for model number E3236 or E3276Affected if Device is a Huawei E3236 or E3276 mobile broadband modem
-
Check firmware versionIn the web admin interface, navigate to Device Information or Settings > Device to view the firmware version. Look for version strings such as '22.146.29.00.00' or '22.265.03.00.00'Affected if Firmware version equals e3236s-2tcpu-22.146.29.00.00 (E3236) or e3276s-150tcpu-22.265.03.00.00 (E3276)
-
Check webui versionIn the web admin interface, locate the web UI version (often shown as webui-13.100.xx.xx.xx) in the device information or about sectionAffected if Webui version equals 13.100.10.00.03 (E3236) or 13.100.09.00.03 (E3276)
-
Verify web admin interface accessibilityDetermine if the device web management interface is reachable over HTTP/HTTPS from network locations. Check router/firewall rules and device LAN/WAN configurationAffected if Web admin interface is accessible from network segments where untrusted browsing could occur
You are affected if you have a Huawei E3236 or E3276 modem running the specific firmware/webui versions listed, with the web admin interface exposed to a network where you browse the internet.

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 dataApply vendor firmware updates (E3276sTCPU-V200R002B470D13SP00C00 or later for E3276; E3236sTCPU-V200R002B146D41SP00C00 or later for E3236). As a workarounds, avoid browsing untrusted sites while logged into the device admin interface and use dedicated management workstations.
