CVE-2014-5774
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 Web Browser & Explorer (aka internetexplorer.browser.webexplorer) application 4 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 Android application 'Web Browser & Explorer' version 4 fails to validate X.509 certificates from SSL servers, allowing man-in-the-middle attackers to present fraudulent certificates and intercept encrypted communications, potentially exposing sensitive user data.

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 Web Browser & Explorer app is installedCheck installed applications on the Android device through Settings > Apps or by using 'adb shell pm list packages' to see if an app with 'web browser' or 'explorer' in the name is presentAffected if The app 'Web Browser & Explorer' is found on the device
-
Verify the installed version is 4.0Access the app info screen in Settings > Apps > Web Browser & Explorer, or use 'adb shell dumpsys package <package_name>' to read the versionInfo. Compare the version number to the affected range (4.0)Affected if The installed version is exactly 4.0
-
Confirm the app uses network/HTTP functionalityReview app permissions in Settings > Apps > Permissions, or check AndroidManifest.xml for INTERNET or network-related permissions granted to the browser appAffected if The app has network permissions enabled, making the SSL validation flaw exploitable for intercepted communications
You are affected if Web Browser & Explorer version 4.0 is installed and has network access permissions, as the certificate validation weakness exists in the application code itself for this specific version.

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 dataAvoid using this vulnerable browser for sensitive transactions until an updated version with proper SSL certificate validation is available, or implement certificate chain validation and pinning in the application code.
