CVE-2017-15393
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 · uneditedInsufficient Policy Enforcement in Devtools remote debugging in Google Chrome prior to 62.0.3202.62 allowed a remote attacker to obtain access to remote debugging functionality via a crafted HTML page, aka a Referer leak.
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 confidenceGoogle Chrome versions prior to 62.0.3202.62 had insufficient policy enforcement in the DevTools remote debugging feature. A remote attacker could craft a malicious HTML page that, through a Referer leak, could obtain unauthorized access to the browser's remote debugging functionality, potentially allowing exfiltration of sensitive data or manipulation of browser sessions.

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 Google Chrome is installedCheck for Chrome installation: On Linux, look for /usr/bin/google-chrome or /opt/google/chrome/google-chrome. On Windows, check C:\Program Files\Google\Chrome\Application\chrome.exe. On macOS, check /Applications/Google Chrome.appAffected if Chrome browser is not present on the system - the vulnerability does not apply
-
Determine the installed Chrome versionOpen Chrome and navigate to chrome://version, or run 'google-chrome --version' from command line on Linux, or check the file properties of chrome.exe on WindowsAffected if Version is earlier than 62.0.3202.62 - the browser is potentially affected
-
Check if remote debugging is enabledLook for Chrome startup flags containing --remote-debugging-port, --remote-debugging-port=0, or inspect chrome://flags for remote debugging related flags. Also check for any enterprise policies enabling debuggingAffected if Remote debugging is enabled (--remote-debugging-port flag is present) - the exploitation path is present in addition to having a vulnerable version
A system is affected only if Google Chrome is installed, the version is earlier than 62.0.3202.62, AND remote debugging functionality is enabled or accessible.

From vendor data62.0.3202.62
Update Google Chrome to version 62.0.3202.62 or later to remediate this vulnerability. Organizations should ensure standard browser patching procedures are followed.
