CVE-2026-21078: CWE-345 (Insufficient Verification of Data Authenticity) in Samsung Mobile Smart Switch
Insufficient verification of data authenticity in Smart Switch trouble scanning mode prior to version 3.7.72.6 allows adjacent attackers to spoof device identity.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-21078) affects Samsung Mobile Smart Switch software versions before 3.7.72.6. It is caused by insufficient verification of data authenticity in the trouble scanning mode, enabling adjacent attackers to spoof the identity of a device. The CVSS 4.7 vector indicates that the attack requires adjacent network access, low attack complexity, no privileges required, user interaction is needed, and it impacts confidentiality, integrity, and availability with low to high scope and impact metrics. No official fix or patch has been confirmed yet.
Potential Impact
An adjacent attacker can spoof device identity due to insufficient verification of data authenticity in the affected Smart Switch versions. This could lead to potential unauthorized actions or data manipulation related to device identity within the trouble scanning mode. The overall impact is rated medium severity based on CVSS 4.7.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should be cautious when using the trouble scanning mode and avoid untrusted adjacent network environments.
