CVE-2018-7956
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 VIP App is a mobile app for Malaysia customers that purchased P20 Series, Nova 3/3i and Mate 20. There is a vulnerability in versions before 4.0.5 that attackers can conduct bruteforce to the VIP App Web Services to get user information.
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 Huawei VIP App versions before 4.0.5 contain a brute-force vulnerability in their backend web services. Attackers can repeatedly attempt requests to enumerate or guess user credentials without adequate rate limiting, account lockout, or CAPTCHA mechanisms, allowing them to obtain user information through automated attacks.

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.
-
Check VIP App version on deviceOpen the device settings, navigate to Apps or Application Manager, find the Huawei VIP App, and view the version information. Alternatively, check in the app's About or Settings section.Affected if The installed VIP App version is lower than 4.0.5 (e.g., 4.0.4, 4.0.3, etc.)
-
Identify device model and firmware versionGo to Settings > About Phone on the Huawei device to view the model number and EMUI/Android firmware version.Affected if The device is a Huawei Mate 20, Nova 3i, or Nova 3, regardless of firmware version
-
Verify backend web service configuration (if you operate the backend)Review the web service endpoints used by the VIP App. Test authentication endpoints by observing whether multiple rapid login attempts trigger rate limiting, account lockout, or CAPTCHA challenges.Affected if The backend does not enforce rate limiting, account lockout, or CAPTCHA on authentication endpoints
A user is affected if they have the VIP App installed with version below 4.0.5, or if they use a Huawei Mate 20, Nova 3i, or Nova 3 device with the bundled vulnerable app version, and the backend lacks proper brute-force protections.

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 data4.0.5
Upgrade VIP App to version 4.0.5 or later. Additionally, implement server-side rate limiting, account lockout policies, and CAPTCHA challenges on the web service endpoints to prevent automated brute-force attacks.
