CVE-2015-2988
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 · uneditedRakuten card App for iOS 5.2.0 through 5.2.4 does not verify SSL certificates which might allow remote attackers to execute man-in-the-middle attacks.
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 Rakuten card App for iOS versions 5.2.0 through 5.2.4 fails to verify SSL certificates during TLS connections, allowing attackers to perform man-in-the-middle attacks and intercept sensitive communications 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 the installed Rakuten Card app versionOn the iOS device, open the App Store app, search for 'Rakuten Card' or 'ラクテンカード', tap on the app, and scroll to the Version information. Alternatively, go to Settings > General > iPhone Storage (or Apps), find the Rakuten Card app, and view the version number.Affected if The displayed version is 5.2.0, 5.2.1, 5.2.2, 5.2.3, or 5.2.4.
-
Confirm the app is the official Rakuten Card appVerify the app name matches 'Rakuten Card' or 'ラクテンカード' and the developer is 'Rakuten Card, Inc.' or 'ラクテンカード株式会社'. Suspiciously named apps claiming to be Rakuten Card should be investigated further.Affected if The installed app is the official Rakuten Card app by Rakuten Card, Inc. and the version falls within 5.2.0-5.2.4.
-
Understand the vulnerability scopeThis vulnerability exists in the app's network layer where SSL certificate validation is disabled or improperly implemented. The app accepts any TLS connection without verifying the server's SSL certificate, allowing attackers on the same network to intercept credentials and session data.Affected if The app version is within the affected range AND the app is used on networks where attackers could perform man-in-the-middle attacks (such as public WiFi).
If the installed Rakuten Card app version is 5.2.0, 5.2.1, 5.2.2, 5.2.3, or 5.2.4 on iOS, the app is vulnerable to SSL certificate verification bypass and communications can be intercepted by attackers on the same network.

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 dataUpdate the Rakuten card app to version 5.2.5 or later which implements proper SSL certificate validation, or implement certificate pinning in the networking layer if patching is not possible.
