CVE-2023-30708
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 · uneditedImproper authentication in SecSettings prior to SMR Sep-2023 Release 1 allows attacker to access Captive Portal Wi-Fi in Reactivation Lock status.
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 confidenceImproper authentication in Samsung's SecSettings allows attackers to bypass Reactivation Lock and access Captive Portal Wi-Fi networks. Reactivation Lock is a security feature that prevents device reactivation without owner credentials; the vulnerability enables unauthorized network access when a device is in this locked state.

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 Android version on Samsung deviceGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The device runs Android 11, Android 12, or Android 13 (exact versions as listed in affected products)
-
Verify Reactivation Lock statusNavigate to Settings > Biometrics and security > Reactivation Lock, or check via 'settings list secure | grep reactivation' commandAffected if Reactivation Lock is enabled on the device (this is the protected state that the bypass targets)
-
Test SecSettings accessibility without credentialsAttempt to access SecSettings via Settings > Biometrics and security > Samsung Security settings folder, or check if the settings are reachable without biometric/PIN verification after lock screenAffected if SecSettings or Reactivation Lock options are accessible without first entering owner credentials after device restart or lock cycle
A Samsung device is affected if it runs Android 11, 12, or 13 AND has Reactivation Lock enabled, with SecSettings accessible without proper authentication verification.

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 · scopedUpdate Samsung devices to SMR (Security Maintenance Release) September-2023 Release 1 or later to patch the authentication bypass in SecSettings.
SMR Sep-2023 Release 1 or later
- Identify the Samsung device model and current Android version
- Check the current security patch level in Settings > About Phone > Software Information > Security patch level
- Update to the latest available Samsung security update: SMR Sep-2023 Release 1 or later
- Verify the update was applied by rechecking the Security patch level in Settings
