Security readout for executives and security teams
Plain-English summary
Samsung Internet before version 14.0.1.62 could show a fake URL in the address bar after a phishing link. The main business risk is users trusting a misleading browser address and entering credentials or sensitive information on an attacker-controlled page.
Executive priority
Treat this as a targeted phishing-enablement issue. Prioritize remediation for mobile users handling credentials, payments, customer data, or privileged business workflows through Samsung Internet.
Technical view
CVE-2021-25419 is described as non-compliance with a recommended secure coding scheme in Samsung Internet. The issue allowed attackers to display a fake URL in the address bar through a phishing URL link. The CVE maps to CWE-703, but no CVSS vector is provided.
Likely exposure
Exposure is limited to users running Samsung Internet versions before 14.0.1.62. Organizations with managed Samsung Android devices, BYOD users, or workflows relying on Samsung Internet should verify browser versions.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. The credible attack context is phishing and UI trust abuse, not direct system compromise based on available evidence.
Researcher notes
Evidence is sparse: no CVSS score, detailed vector, affected platform matrix, or exploitation evidence is included. The issue appears to affect browser UI trust and URL display integrity. Do not assume impact on other browsers or WebView without vendor evidence.
Mitigation direction
- Update Samsung Internet to version 14.0.1.62 or later.
- Check Samsung's June 2021 guidance for any additional remediation notes.
- Use mobile device management to enforce browser updates where possible.
- Educate users not to trust links solely by visible address-bar text.
Validation and detection
- Inventory devices with Samsung Internet installed and record versions.
- Flag installations earlier than 14.0.1.62.
- Review mobile management controls for browser update enforcement.
- Check phishing reports involving Samsung Internet address-bar inconsistencies.
