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.
-
Identify Mi Xiaomi Cloud application versionCheck the application settings, about page, or installed package version (commonly found in Settings > About > Version, or in the app's APK/IPA metadata)Affected if The installed version is 1.12.0.0.25 or any earlier version (1.12.0.0.25 and below)
-
Locate the Webview componentInspect the application binaries or runtime components for the Webview module used for rendering web content within the appAffected if The Webview component is present and used for displaying web content within the application
-
Check whitelist configuration accessAccess the whitelist checking function in the cloud service settings or configuration panel where URL schemes are validatedAffected if The whitelist validation feature is accessible and allows input of custom URL schemes
You are affected if Mi Xiaomi Cloud version is 1.12.0.0.25 or lower AND the Webview component is actively used with an accessible whitelist configuration that can accept javascript: URLs.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedFix the Webview whitelist validation to reject javascript: and other dangerous URL schemes; implement HttpOnly and Secure flags on session cookies to prevent exfiltration.
Version > 1.12.0.0.25 (specific fixed release to be confirmed from trust.mi.com)
- 1. Identify the Xiaomi Cloud application version currently installed
- 2. Check Xiaomi's official security advisory (trust.mi.com) or app store listing for the latest version
- 3. Upgrade Xiaomi Cloud application to version higher than 1.12.0.0.25
- 4. Verify the upgrade successfully replaces the vulnerable WebView component
- 5. Test that the application functions normally after upgrade
- 6. Clear browser/application cache to remove any potentially compromised session data
