CVE-2016-4830
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 · uneditedSushiro App for iOS 2.1.16 and earlier and Sushiro App for Android 2.1.16.1 and earlier do not verify SSL certificates.
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 Sushiro mobile applications for iOS (version 2.1.16 and earlier) and Android (version 2.1.16.1 and earlier) fail to validate SSL certificates during network communications, allowing man-in-the-middle attackers to intercept, read, and modify sensitive data transmitted between the app and backend servers.

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 Sushiro app is installed on iOS devicesCheck device inventory or MDM solution for the app 'Sushiro' or 'Akindo Sushiro Sushiro' on iOS devices in your environmentAffected if The app is found on any iOS device in your inventory
-
Check installed iOS app versionUse iOS device management tools or check the app version directly on the device. Affected version is 2.1.16 and earlierAffected if Installed version is 2.1.16 or lower
-
Identify if Sushiro app is installed on Android devicesCheck device inventory or MDM solution for the app 'Sushiro' or 'Akindo Sushiro Sushiro' on Android devices in your environmentAffected if The app is found on any Android device in your inventory
-
Check installed Android app versionUse Android device management tools or check the app version directly on the device. Affected version is 2.1.16.1 and earlierAffected if Installed version is 2.1.16.1 or lower
-
Verify SSL certificate validation is implementedPerform static analysis of the app binary or conduct a man-in-the-middle test to observe whether the app accepts self-signed or invalid certificates without warningAffected if The app accepts connections to the backend server when SSL/TLS certificates are invalid or missing, indicating certificate validation is not being performed
You are affected if the Sushiro mobile app (iOS version 2.1.16 or earlier, or Android version 2.1.16.1 or earlier) is installed on devices in your environment and the app does not properly validate SSL certificates.

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 SSL/TLS certificate validation with certificate pinning in both iOS and Android versions to ensure the app verifies the identity of the server before establishing secure connections.
