CVE-2015-2968
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 · uneditedLINE@ for Android version 1.0.0 and LINE@ for iOS version 1.0.0 are vulnerable to MITM (man-in-the-middle) attack since the application allows non-SSL/TLS communications. As a result, any API may be invoked from a script injected by a MITM (man-in-the-middle) attacker.
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 confidenceLINE@ mobile applications for Android and iOS version 1.0.0 fail to enforce SSL/TLS encryption for network communications, allowing man-in-the-middle attackers to intercept, modify, and inject malicious API requests. The lack of secure transport layer implementation enables script injection and arbitrary API invocation.

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 LINE@ app is installedOn Android: Go to Settings > Apps > look for 'LINE@' in the app list. On iOS: Go to Settings > General > iPhone Storage > look for 'LINE@' in the app list.Affected if The LINE@ application is found on the device
-
Identify installed version of LINE@On Android: Go to Settings > Apps > LINE@ > App info > look for 'Version' or 'Version name'. On iOS: Go to App Store > search for LINE@ > tap the app > check the version number displayed.Affected if The version displayed is 1.0.0
-
Compare version against affected rangeIf the version shown is exactly 1.0.0, the device is running the vulnerable version.Affected if Installed version equals 1.0.0 exactly
-
Verify network communication security (optional verification)Use a network proxy or packet capture tool (like Wireshark or a MITM proxy) to monitor network traffic from the LINE@ app. Check if requests go to HTTP (port 80) instead of HTTPS (port 443).Affected if Network traffic from the app uses unencrypted HTTP instead of HTTPS
A user is affected if LINE@ version 1.0.0 is installed on their Android or iOS device, as this version lacks SSL/TLS enforcement for network communications.

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 SSL/TLS enforcement for all network communications and consider adding certificate pinning to prevent MITM attacks. Update both Android and iOS applications to a version where secure communications are mandatory.
