CVE-2018-7950
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 · high confidenceThe iBMC (Intelligent Baseboard Management Controller) on Huawei servers contains a JSON injection vulnerability due to insufficient input validation. An authenticated remote attacker can inject malicious JSON payload to modify the administrator password and gain full management privileges of the affected 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 if the server is a Huawei model with iBMCCheck the server hardware model (1288h V5, 2288h V5, 2488 V5, Ch121 V3, Ch121l V3, Ch121l V5, Ch121 V5, or Ch140 V3) and confirm iBMC (Intelligent Baseboard Management Controller) is presentAffected if The server is one of the listed Huawei models and has iBMC firmware installed
-
Check the iBMC firmware versionAccess the iBMC web interface or use the command line (e.g., 'ipmcget -t version' or similar iBMC CLI command) to retrieve the firmware versionAffected if The firmware version matches exactly 100r005c00 for V5 models or 100r001c00 for V3/V5 Ch models (these are the affected versions listed)
-
Verify iBMC remote management interface is accessibleCheck if the iBMC web interface (HTTPS/HTTP port) or IPMI over network is reachable from network segments outside the server itselfAffected if iBMC is network-accessible and an attacker could potentially authenticate to it
-
Confirm iBMC user authentication is enabledReview iBMC user accounts and authentication settings to ensure user accounts exist and remote authentication (local or LDAP/RADIUS) is configuredAffected if Remote authentication is enabled, as the vulnerability requires an authenticated attacker to inject the malicious JSON payload
You are affected if you run any of the listed Huawei server models with iBMC firmware version 100r005c00 or 100r001c00, have iBMC network-accessible, and allow remote authentication.

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 firmware/patch for iBMC from Huawei's security advisory. If immediate patching is not feasible, restrict network access to the iBMC management interface to trusted IP addresses and enforce strong authentication mechanisms.
