CVE-2021-25448Network attack vector

Arbitrary webpage loading via uncontrolled WebView access

Published Aug 5, 2021 · Updated Aug 3, 2024

Improper access control in Samsung Smart Touch Call before 1.0.0.5 allows attackers to load arbitrary webpages through its WebView. The WebView processes a webpage-loading request without enforcing the intended access restriction; Samsung has not identified the affected function or request path. The public record does not identify the initiating interface or necessary device state; the bounded result is attacker-chosen web content rendered in the app.
