CVE-2023-49246
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 · uneditedUnauthorized access vulnerability in the card management module. Successful exploitation of this vulnerability may affect service confidentiality.
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 confidenceAn unauthorized access vulnerability exists in the card management module that allows attackers to bypass authentication or authorization controls. The CVSS 7.5 score indicates the vulnerability is remotely exploitable and primarily impacts service confidentiality, likely allowing unauthorized viewing of card data or cardholder information.

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 Huawei Emui versionGo to Settings > About Phone > Version on the Huawei device and identify the EMUI build numberAffected if The installed EMUI version equals 11.0.1, 12.0.0, or 13.0.0
-
Check Huawei HarmonyOS versionGo to Settings > About Phone > Version on the Huawei device and identify the HarmonyOS build numberAffected if The installed HarmonyOS version equals 2.0.0, 3.0.0, 3.1.0, or 4.0.0
-
Identify card management module presenceCheck if any card management, wallet, or payment application is installed and accessible on the deviceAffected if A card management or digital wallet application is installed and accessible on the device
-
Verify authentication requirement for card accessAttempt to access any card management feature without providing credentials or authentication to see if the module permits unauthenticated accessAffected if The card management module allows access to card data or cardholder information without requiring authentication or authorization
You are affected if your Huawei device runs EMUI 11.0.1, 12.0.0, or 13.0.0 or HarmonyOS 2.0.0, 3.0.0, 3.1.0, or 4.0.0 and the card management module is accessible without 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 dataImplement proper authentication and authorization controls in the card management module. Ensure all access to card data requires valid authentication and appropriate authorization checks for the requested operation.
