CVE-2014-5655
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 CM Browser - Fast & Secure (aka com.ksmobile.cb) application 5.0.50 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 CM Browser Android application version 5.0.50 fails to validate X.509 certificates from SSL servers, allowing man-in-the-middle attackers to intercept encrypted communications by presenting forged certificates and spoof legitimate servers to steal sensitive 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.
-
Locate the CM Browser application on the Android deviceOpen Settings > Apps on the Android device and search for 'CM Browser' or 'Cmcm Cm Browser' in the installed applications listAffected if CM Browser is not installed on the device, then this CVE does not apply
-
Identify the installed version of CM BrowserIn Settings > Apps > CM Browser, locate the Version information displayed under the app name. Alternatively, use an APK inspection tool to extract the versionName from the installed packageAffected if The installed version is 5.0.50 exactly, then the device is affected by this vulnerability
-
Confirm the application name matches the vulnerable packageVerify the application is specifically 'CM Browser Fast & Secure' by CMcm (or 'Cmcm Cm Browser') and not a similarly named third-party browserAffected if The installed app is CM Browser version 5.0.50 by CMcm, the SSL certificate validation flaw is present and the app is vulnerable to man-in-the-middle attacks
A user is affected if CM Browser Fast & Secure version 5.0.50 by CMcm is installed on their Android device, as this version fails to validate X.509 certificates from SSL servers.

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 dataReplace the vulnerable application version with an updated version that properly implements SSL/TLS certificate chain validation, and advise users to avoid untrusted networks until the fix is applied.
