CVE-2014-7643
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 · uneditedThe C.R. Group (aka com.c.r.group) application 1.0 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
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 C.R. Group Android application version 1.0 fails to validate X.509 certificates during SSL/TLS connections, allowing man-in-the-middle attackers to intercept encrypted communications by presenting fraudulent certificates. This enables credential theft, session hijacking, and data exfiltration.

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 C.R. Group Android app is installedOn the Android device, go to Settings > Apps or use ADB command: `adb shell pm list packages | grep -i crgroup`Affected if The package named Crgroup Lb C.r. Group or containing 'crgroup' is found on the device
-
Verify the installed app versionUse ADB: `adb shell dumpsys package <package_name>` or check the app's version in Google Play Store / app info screenAffected if The installed version matches version 1 (or the package name matches the affected product)
-
Confirm the app makes network connectionsUse network monitoring tools (e.g., Android Studio Profiler, tcpdump, or a proxy like Burp Suite) to observe if the app initiates any HTTPS requestsAffected if The app transmits data over HTTPS connections without proper certificate validation
-
Test for certificate validation failureConfigure a proxy with an untrusted/self-signed certificate and attempt to intercept the app's traffic. If the app connects successfully without certificate warnings, validation is bypassedAffected if The app accepts connections to the proxy with an untrusted certificate, indicating X.509 validation is not being performed
You are affected if the C.R. Group Android app (version 1 or the specific package) is installed on your device and accepts HTTPS connections without validating the server's certificate chain.

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 certificate chain validation in all network requests, preferably using certificate pinning for critical endpoints, and ensure all HTTPS connections validate the server's certificate against trusted CAs.
