CVE-2024-23729Public exploitNetwork attack vector

JavaScript execution via exported activity intent

Published Aug 19, 2024 · Updated Aug 20, 2024

Cross-site scripting in HeyTap Internet Browser 45.10.3.4.1 allows remote attackers to execute JavaScript through an Android intent. The exported com.android.browser.RealBrowserActivity accepts an ACTION_VIEW intent containing a javascript URI without requiring permission and executes it in the browser context. Exploitation requires user interaction or an unprivileged malicious app to dispatch the intent, and the resulting script runs with the browser application's access.
