CVE-2022-48621
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 · uneditedVulnerability of missing authentication for critical functions in the Wi-Fi 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 confidenceThis vulnerability involves missing authentication controls on critical functions within a Wi-Fi module. An unauthenticated attacker could potentially invoke sensitive operations or access confidential data transmitted through or managed by the Wi-Fi module. The CVSS 7.5 score reflects the high confidentiality impact from unauthorized access to these unprotected functions.

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 installed OS versionGo to Settings > About Phone on the Huawei device and locate the version field. For EMUI, look for 'EMUI 12.0.0' or 'EMUI 13.0.0'. For HarmonyOS, look for '2.0.0', '2.1.0', '3.0.0', '3.1.0', or '4.0.0'.Affected if The version exactly matches 12.0.0 or 13.0.0 for EMUI, or 2.0.0, 2.1.0, 3.0.0, 3.1.0, or 4.0.0 for HarmonyOS.
-
Confirm the device uses a Wi-Fi moduleVerify that Wi-Fi functionality is present on the device by checking Settings > Network & Internet > Wi-Fi or similar menu path, or by observing Wi-Fi related system processes running.Affected if Wi-Fi capability exists on the device, as the vulnerability targets the Wi-Fi module's critical functions.
-
Check if Wi-Fi is actively configuredReview whether the device has any Wi-Fi networks saved or has been used to connect to wireless networks. Look in Settings > Network & Internet > Wi-Fi > Saved Networks.Affected if The device has Wi-Fi configuration history or is actively using Wi-Fi, as the flaw affects data transmitted through the Wi-Fi module.
-
Review system logs for unauthorized Wi-Fi access attemptsAccess device logs through the diagnostic menu (dial *#*#2846579#*#* on some Huawei devices) or check the HiSuite log directory on a connected PC for any unusual Wi-Fi function invocations.Affected if Unexpected or unauthenticated Wi-Fi module function calls appear in the logs, indicating potential exploitation.
A user is affected if their Huawei device runs EMUI 12.0.0/13.0.0 or HarmonyOS 2.0.0/2.1.0/3.0.0/3.1.0/4.0.0 and utilizes Wi-Fi functionality, as the vulnerability exists in the Wi-Fi module of these specific versions.

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 robust authentication mechanisms for all critical functions in the Wi-Fi module, enforce proper access controls, and consider firmware updates from the vendor if patches are available.
