CVE-2018-7903
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 · uneditedHuawei 1288H V5 and 288H V5 with software of V100R005C00 have a JSON injection vulnerability. An authenticated, remote attacker can launch a JSON injection to modify the password of administrator. Due to insufficient verification of the input, this could be exploited to obtain the management privilege of the system.
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 confidenceJSON injection vulnerability in Huawei 1288H V5 and 288H V5 servers (V100R005C00) allows authenticated remote attackers to manipulate JSON input and modify the administrator password. Insufficient input validation permits privilege escalation to full management control of the system.

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 server modelCheck the server model label or use IPMI/iBMC to query the product name. Confirm it is either Huawei 1288H V5 or 2288H V5.Affected if The server model is Huawei 1288H V5 or 2288H V5.
-
Check firmware versionAccess the iBMC web interface or use IPMI command 'ipmitool -I lanplus -H <iBMC_IP> -U admin -P <password> raw' to retrieve the firmware version. Compare against v100r005c00.Affected if The firmware version is exactly v100r005c00.
-
Verify iBMC management interface is accessibleCheck if TCP port 443 or 80 is open on the iBMC IP address. Run 'nmap -p 443,80 <iBMC_IP>' or check network firewall rules.Affected if The iBMC web interface is exposed on the network.
-
Review account for unauthorized changesLog into iBMC and navigate to User Management or check system logs for password change events. Look for unexpected administrator accounts or recent password modifications.Affected if New administrator accounts exist or password changes occurred without legitimate admin action.
The environment is affected if the server is a Huawei 1288H V5 or 2288H V5 running firmware version v100r005c00 with the iBMC management interface accessible, and exploitation may be indicated by unauthorized account changes.

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 Huawei vendor patches when available; restrict management interface network access to trusted IP addresses only; monitor for unauthorized account changes.
