CVE-2020-9137
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 privilege escalation vulnerability in some versions of CloudEngine 12800,CloudEngine 5800,CloudEngine 6800 and CloudEngine 7800. Due to insufficient input validation, a local attacker with high privilege may execute some specially crafted scripts in the affected products. Successful exploit will cause privilege escalation.
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 confidenceThis is a local privilege escalation vulnerability in Huawei CloudEngine 12800, 5800, 6800, and 7800 switches. Due to insufficient input validation, a local attacker who already has high privileges can execute specially crafted scripts to gain elevated privileges beyond their current level.

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 modelExecute 'display device' or 'display version' command via console/SSH to retrieve the device model numberAffected if Model is CloudEngine 12800, 5800, 6800, or 7800
-
Retrieve firmware versionExecute 'display version' command to obtain the exact firmware version string (e.g., v200r002c50spc800)Affected if Version matches any of: v200r002c50spc800, v200r003c00spc810, v200r005c00spc800, v200r005c10spc800, v200r005c20spc800, v200r019c00spc800, v200r019c10spc800
-
Confirm script execution capabilityCheck if the device has script-related features enabled by reviewing current configuration with 'display current-configuration' and look for script or TCL command configurationsAffected if Script execution features are enabled and device firmware version matches the affected list
The device is affected if it is a CloudEngine 12800/5800/6800/7800 running any of the listed firmware versions and script execution functionality is available to high-privilege users.

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 the vendor-supplied security patch for your specific CloudEngine model and version. Restrict local administrative access to trusted personnel and monitor for unauthorized script execution.
