CVE-2014-5852
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 Kakao (aka com.com2us.tinypang.kakao.freefull2.google.global.android.common) application 2.11.1.0 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 Kakao Android app version 2.11.1.0 fails to validate X.509 certificates from SSL servers, allowing man-in-the-middle attackers to intercept encrypted communications by presenting fraudulent certificates and harvest 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 Kakao app on the Android deviceOpen Android Settings > Apps > Application Manager, then search for 'Kakao' or '카카오' in the installed applications listAffected if The Kakao app by Withhive is present on the device
-
Determine the installed version of the Kakao appTap on the Kakao app in the application list, then view the 'Version' or 'Version info' field displayed under the app nameAffected if The displayed version number is exactly 2.11.1.0
-
Verify network traffic inspection capabilityInstall a network proxy tool such as Burp Suite or OWASP ZAP on a proxy machine, configure the Android device to route traffic through the proxy, and attempt to intercept SSL/TLS traffic from the Kakao appAffected if The proxy is able to intercept and decrypt traffic from the Kakao app without any certificate errors or warnings being presented to the user, indicating the app accepts the proxy's fraudulent certificate
-
Check for certificate validation behaviorUse a man-in-the-middle proxy setup with an untrusted or self-signed certificate and attempt to establish an SSL connection to a server through the Kakao appAffected if The app successfully establishes encrypted connections without rejecting the invalid certificate, confirming certificate validation is not being performed
A user is affected if the Kakao app version installed on their Android device is exactly 2.11.1.0 and the app accepts invalid or untrusted SSL certificates during network communication.

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 using Android's standard TrustManager or employ certificate pinning to ensure the app only trusts expected certificates.
