CVE-2012-5970
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 · uneditedThe Huawei E585 device allows remote attackers to cause a denial of service (NULL pointer dereference and device outage) via crafted HTTP requests, as demonstrated by unspecified vulnerability-scanning software.
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 Huawei E585 mobile hotspot device contains a NULL pointer dereference vulnerability in its embedded HTTP server. Remote attackers can send specially crafted HTTP requests that trigger the NULL pointer dereference, causing the device to crash and become unavailable.

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 modelCheck the physical device or network inventory for Huawei E585 or Huawei E585u 82 mobile hotspot devicesAffected if The device model is Huawei E585 or Huawei E585u 82
-
Verify HTTP server is accessibleAttempt to access the device HTTP interface on the typical admin port (usually port 80 or 8080) by entering the device IP in a web browserAffected if The HTTP interface loads and responds to requests
-
Check network exposure of the HTTP serviceDetermine if the device HTTP port is exposed to untrusted networks (internet-facing or accessible from guest/untrusted VLANs) by reviewing firewall rules and network segmentationAffected if The HTTP port is accessible from networks outside the trusted administrative zone
If you have a Huawei E585 or E585u 82 device with its HTTP interface accessible to untrusted networks, your environment is affected by this vulnerability and could be crashed remotely.

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 dataSince this is a hardware/firmware vulnerability in an older Huawei device, primary mitigation is to replace the affected device with a current model or apply any available firmware updates. Network-level mitigations include restricting HTTP access to the device through firewall rules or placing it behind a controlled gateway.
