Security readout for executives and security teams
Plain-English summary
This flaw could let someone with physical access to an unlocked Samsung device view or alter Samsung Pass data in a specific device state. The business risk is mainly lost, borrowed, or unattended unlocked phones, not remote compromise.
Executive priority
Treat as a moderate mobile data-protection issue. Prioritize managed devices used for sensitive business access, executives, finance, and administrators, especially where lost or unattended unlocked phones are plausible.
Technical view
CVE-2023-30677 is an improper access control issue in Samsung Pass before version 4.2.03.1. CVSS 3.1 is 6.1 with physical attack vector, low complexity, no privileges, no user interaction, high confidentiality and integrity impact, and no availability impact.
Likely exposure
Exposure is limited to Samsung devices running Samsung Pass before 4.2.03.1. The provided sources do not identify specific device models, Android versions, enterprise configurations, or whether Samsung Pass must be actively used.
Exploitation context
The sources describe a physical attacker accessing Samsung Pass data when an unlocked device is in a certain state. CISA KEV is false, and the bundle provides no evidence of active exploitation or public exploit availability.
Researcher notes
The CVSS vector is physical-only but has high confidentiality and integrity impacts. Source evidence does not define the exact unlocked-device state, affected models, exploit maturity, or detailed remediation beyond the fixed Samsung Pass version threshold.
Mitigation direction
- Update Samsung Pass to version 4.2.03.1 or later where available.
- Review Samsung Mobile July 2023 security guidance for vendor-specific instructions.
- Enforce short screen lock timeouts and strong device unlock policies.
- Use MDM controls for remote lock or wipe of lost devices.
- Remind users not to leave unlocked devices unattended.
Validation and detection
- Inventory Samsung devices with Samsung Pass installed.
- Confirm Samsung Pass version is 4.2.03.1 or later.
- Check mobile management compliance for lock timeout and unlock strength.
- Identify unmanaged Samsung devices with access to business accounts.
- Monitor vendor advisories for any updated affected-version details.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
