CVE-2016-8501
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 · uneditedSecurity WiFi bypass in Yandex Browser from version 15.10 to 15.12 allows remote attacker to sniff traffic in open or WEP-protected wi-fi networks despite of special security mechanism is enabled.
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 confidenceYandex Browser versions 15.10 through 15.12 contain a security bypass vulnerability where a special security mechanism intended to protect users on open or WEP-protected WiFi networks can be circumvented, allowing a remote attacker to sniff network traffic.

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.
-
Verify Yandex Browser is installedCheck for Yandex Browser executable: On Windows, look in Program Files\Yandex\YandexBrowser\ or check Add/Remove Programs. On macOS, check /Applications for Yandex Browser.app.Affected if Yandex Browser is not installed on the system.
-
Identify installed Yandex Browser versionOpen Yandex Browser, navigate to browser://settings (or Menu > Settings), and find the version number typically displayed at the bottom of the About section. Alternatively, right-click the browser shortcut and select Properties > Details to view the version.Affected if The installed version falls within 15.10.x through 15.12.x range, specifically if it matches or exceeds 15.10 but is lower than 15.13.
-
Confirm the Protect feature statusLook for the shield icon in the browser's address bar or check Settings > Security > Protect (or Secure Network) to see if the WiFi security protection is enabled.Affected if The Protect feature is enabled and the browser version is in the affected range (15.10-15.12), as this indicates the vulnerable security mechanism is active.
-
Check for network traffic protection moduleIn the browser, navigate to chrome://components or browser://components (depending on interface) and look for a network protection or secure proxy component. Also inspect Settings for any 'Secure Network' or 'WiFi Protection' toggle.Affected if A network protection module is present and active while the browser version remains in the affected 15.10-15.12 range.
A user is affected if Yandex Browser versions 15.10 through 15.12 are installed AND the built-in network protection for open/WiFi networks is enabled, allowing potential traffic sniffing by remote attackers on untrusted networks.

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 dataUpgrade Yandex Browser to a version newer than 15.12, or use an alternative browser for sensitive operations on untrusted networks until the upgrade is available.
