CVE-2014-6691
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 UC Browser HD (aka com.uc.browser.hd) application 3.3.1.469 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 UC Browser HD Android app version 3.3.1.469 does not validate X.509 certificates from SSL servers, allowing man-in-the-middle attackers to intercept encrypted communications by presenting fraudulent certificates and steal 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.
-
Check if UC Browser HD is installedOn the Android device, go to Settings > Apps > Apps, or check through your MDM/EMM console for installed applications. Look for 'UC Browser HD' or 'Ucweb Uc Browser HD' in the application list.Affected if UC Browser HD is present on the device
-
Verify the installed version numberIn Settings > Apps > UC Browser HD, scroll to the 'Version' or 'App info' section to display the installed version number. Alternatively, query via ADB: adb shell dumpsys package com.UCMobile.lite or check your MDM inventory for the version attribute.Affected if The displayed version is 3.3.1.469
-
Confirm certificate validation is not performed by the appThis is intrinsic to the vulnerable version - the app does not validate X.509 certificates. No additional configuration check is needed; the vulnerability exists by design in version 3.3.1.469.Affected if The app is running and processes HTTPS traffic
You are affected if UC Browser HD version 3.3.1.469 is installed on any Android device in your environment and that device uses the app to access HTTPS websites.

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 dataUsers should avoid using this application on untrusted networks; organizations should consider blocking the application or implementing network-level SSL inspection controls until a patched version is available from the vendor.
