CVE-2020-14126
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 · uneditedInformation leakage vulnerability exists in the Mi Sound APP. This vulnerability is caused by illegal calls of some sensitive JS interfaces, which can be exploited by attackers to leak sensitive 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 confidenceAn information leakage vulnerability exists in the Mi Sound mobile application where sensitive JavaScript interfaces are exposed to illegal/unauthorized calls. Attackers can exploit these exposed JS interfaces to extract sensitive information from the application or connected services.

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.
-
Verify Mi Sound app is installedOn Android: Go to Settings > Apps > find Mi Sound in the app list. On iOS: Check the installed apps list or search for Mi Sound.Affected if Mi Sound mobile application is present on the device
-
Check installed Mi Sound version numberOn Android: Settings > Apps > Mi Sound > App info displays version. On iOS: Long press app icon > App Store link shows version, or check in device settings under iTunes & App Store settings.Affected if Application is installed and version is visible
-
Compare version against affected rangeCompare your installed version number to the affected range: any version less than or equal to 2.2.40 is within the affected range.Affected if Installed version is 2.2.40 or lower (for example, 2.2.38, 2.2.30, 2.0.0)
-
Confirm vulnerability is exploitable in your contextThis vulnerability requires the app to have exposed JavaScript interfaces - this is inherent to affected versions. The flaw exists if the app processes untrusted web content or connects to potentially malicious services.Affected if You use Mi Sound version 2.2.40 or earlier and the app interacts with web content or external services
You are affected if Mi Sound version 2.2.40 or lower is installed on your device, as this version contains the exposed sensitive JavaScript interfaces.

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 dataSecure or remove exposed sensitive JavaScript interfaces by implementing proper authentication, authorization checks, and input validation on all JS interface methods; consider using whitelisting for allowed method calls.
