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 installed Cybozu KUNAI versionOpen the app on the Android device, navigate to Settings > About/Version, or check the version displayed on the app's main screenAffected if The version displayed is 3.0.20 or 3.0.21
-
Verify version via package managerUse ADB command: adb shell dumpsys package <package_name> | grep versionName, or check the app info in Android Settings > Apps > Cybozu KUNAIAffected if The versionName field shows 3.0.20 or 3.0.21
-
Confirm remote network exposureReview if the Android device or app is configured to accept incoming network connections, or if the app is used in a configuration where it processes requests from remote/untrusted network sourcesAffected if The app is exposed to remote network requests and the version is 3.0.20 or 3.0.21
A user is affected if Cybozu KUNAI for Android is installed at version 3.0.20 or 3.0.21 and the app processes network requests from remote sources.

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 · scopedUpgrade to a patched version beyond 3.0.21 if available; otherwise, restrict network exposure and monitor for unusual request patterns to mitigate exploitation.
Kunai 3.0.22 or later
- 1. Check the current installed version of Cybozu KUNAI for Android on all affected devices.
- 2. Navigate to the official Cybozu download page or respective app store (Google Play).
- 3. Download and install the latest version of Cybozu KUNAI for Android.
- 4. Verify the installed version is newer than 3.0.21 after update completion.
