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 · moderate confidence

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate 360 Speed Browser installation
    Search for the browser executable (usually named 360speed.exe or similar) in common installation paths: C:\Program Files\360\360SpeedBrowser\ or C:\Users\[User]\AppData\Local\Programs\360SpeedBrowser\
    Affected if The executable 360speed.exe is found on the system
  2. Get the installed version
    Right-click the executable, select Properties, then go to the Details tab to view the File Version or Product Version field
    Affected if The Product Version or File Version is exactly 12.0.1247.0
  3. Verify browser is in a user-writable location
    Check the folder permissions on the browser installation directory - right-click the folder, select Properties, go to Security tab, and verify if standard users have Write or Modify permissions
    Affected if The browser is installed in a directory where standard user accounts can write or modify files (such as a user-specific AppData folder or an unprotected Program Files location)

A user is affected only if 360 Speed Browser version 12.0.1247.0 is installed and the application or its DLL search path resides in a directory writable by untrusted users.
