CVE-2018-7951
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 iBMC (Intelligent Baseboard Management Controller) of some Huawei servers have a JSON injection vulnerability due to insufficient input validation. An authenticated, remote attacker can launch a JSON injection to modify the password of administrator. Successful exploit may allow attackers 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 · moderate confidenceThe iBMC (Intelligent Baseboard Management Controller) in Huawei servers contains a JSON injection vulnerability caused by insufficient input validation. An authenticated remote attacker can exploit this flaw to inject malicious JSON payloads during password modification operations, allowing them to overwrite the administrator password and gain full management 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 the server model and iBMC firmware versionAccess the iBMC web interface under 'System Information' or use the iBMC CLI command 'show version' to retrieve the firmware version. Alternatively, use IPMI commands to query BMC information.Affected if The server is a Huawei 1288h V5, 2288h V5, 2488 V5, Ch121 V3, Ch121l V3, Ch121l V5, Ch121 V5, or Ch140 V3 model
-
Compare installed firmware version to affected versionsMatch the installed iBMC firmware version against the affected versions: 100r005c00 applies to 1288h V5, 2288h V5, and 2488 V5; 100r001c00 applies to Ch121 V3, Ch121l V3, Ch121l V5, Ch121 V5, and Ch140 V3.Affected if The installed iBMC firmware version equals exactly 100r005c00 or 100r001c00 for the corresponding model
-
Confirm iBMC remote management interface is enabledVerify whether the iBMC web interface or IPMI over LAN is accessible on the network. Check network settings in the iBMC web UI or use network scanning to detect open ports 443 or 623.Affected if The iBMC management interface is network-accessible (ports 443 for web UI or 623 for IPMI)
-
Determine if password modification functionality is exposedReview iBMC access logs or network traffic to identify if password modification API endpoints are reachable. The vulnerability is exploited through JSON injection during password change operations.Affected if The iBMC password modification interface is accessible to authenticated users on the network
Environment is affected if the Huawei server model and iBMC firmware version match the listed affected combinations AND the iBMC management interface is network-accessible.

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 security patches for affected iBMC versions when available. Until patched, restrict iBMC management interface access to trusted networks and monitor for unauthorized password change attempts.
