CVE-2017-8135
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 FusionSphere OpenStack with software V100R006C00 and V100R006C10 has a command injection vulnerability due to the insufficient input validation on four TCP listening ports. An unauthenticated attacker can exploit the vulnerabilities to gain root privileges by sending some messages with malicious commands.
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 confidenceFusionSphere OpenStack V100R006C00 and V100R006C10 contains a command injection vulnerability caused by insufficient input validation on four TCP listening ports. An unauthenticated remote attacker can send specially crafted messages containing malicious commands to execute arbitrary code with root privileges.

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 FusionSphere OpenStack installationRun 'cat /etc/huawei_fusionsphere_version' or check product documentation to confirm FusionSphere OpenStack is installed on the systemAffected if The product is confirmed to be Huawei FusionSphere OpenStack
-
Check installed versionExecute 'swmgr -v' or access the FusionSphere management console to retrieve the exact version numberAffected if The installed version is V100R006C00 or V100R006C10
-
Identify vulnerable TCP listening portsUse 'netstat -tlnp' or 'ss -tlnp' to list all listening TCP ports on the system and correlate with FusionSphere OpenStack servicesAffected if Four specific TCP listening ports associated with FusionSphere OpenStack services are found to be listening and exposed
-
Assess network exposure of vulnerable portsReview firewall rules using 'iptables -L' or check network segmentation configurations to determine if these TCP ports are accessible from untrusted networksAffected if The vulnerable TCP ports are accessible from untrusted or external network segments without proper access controls
The system is affected if it runs FusionSphere OpenStack version V100R006C00 or V100R006C10 AND has the four vulnerable TCP listening ports exposed to untrusted network access.

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 dataRestrict network access to the affected TCP ports and apply vendor-provided patches or updates to FusionSphere OpenStack. If patches are unavailable, consider network segmentation to limit exposure to trusted users.
