CVE-2020-9124
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 · uneditedThere is a memory leak vulnerability in some versions of Huawei CloudEngine product. An unauthenticated, remote attacker may exploit this vulnerability by sending specific message to the affected product. Due to not release the allocated memory properly, successful exploit may cause memory leak.
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 confidenceMemory leak vulnerability in Huawei CloudEngine products where an unauthenticated remote attacker can send specific messages to cause improper memory deallocation, leading to memory exhaustion.

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 CloudEngine modelRun the command `display device` or check the physical device label to confirm the model is one of: CloudEngine 12800, 5800, 6800, or 7800Affected if Model is not one of these four CloudEngine series
-
Check firmware versionRun the command `display version` to retrieve the installed firmware versionAffected if Version matches any of: v200r002c50spc800, v200r003c00spc810, v200r005c00spc800, or v200r005c10spc800
-
Verify network accessibilityConfirm the device management interface or network protocols are reachable from untrusted networks by reviewing interface configurations with `display ip interface` or `display current-configuration interface`Affected if Management or network interfaces are exposed to untrusted networks without access controls
The environment is affected if the device is a CloudEngine 12800/5800/6800/7800 running firmware version v200r002c50spc800, v200r003c00spc810, v200r005c00spc800, or v200r005c10spc800 and the management interface is network-accessible to untrusted sources.

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-provided security patches for affected CloudEngine versions. If patches unavailable, implement network segmentation and restrict management interface access to trusted sources to reduce exposure.
