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 Smart Touch Call app is installedOn the Android device, run 'pm list packages | grep -i touch' or 'pm list packages' and search for Smart Touch Call related packageAffected if Smart Touch Call app is found on the device
-
Determine installed version of Smart Touch CallRun 'dumpsys package <package_name>' for the Smart Touch Call app to extract the versionName and versionCode fieldsAffected if Version returned is lower than 1.0.0.5 (or versionCode is less than the value corresponding to 1.0.0.5)
-
Confirm webview component is accessibleInspect app permissions via 'dumpsys package <package_name>' and check for INTERNET permission and webview-related components in the app manifestAffected if App has INTERNET permission and contains webview components (WebView, WebViewClient, or WebChromeClient usage)
-
Test URL validation behavior in webviewIf possible, analyze app traffic or use a dynamic analysis tool to observe if the webview accepts arbitrary URLs without restrictionAffected if Webview loads URLs from untrusted sources or allows navigation to arbitrary domains
User is affected if Smart Touch Call app is installed with version below 1.0.0.5 and contains webview components with internet permission.

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 data1.0.0.5
Upgrade Smart Touch Call to version 1.0.0.5 or later which contains proper access controls; alternatively implement URL whitelist/allowlist validation in the webview component.
