Executive Summary

CVE-2025-68709 affects the SailingLab AppLock (com.alpha.applock) version 4.3.8 for Android. It allows a local attacker to execute arbitrary JavaScript code through the BrowserMainActivity component by sending specially crafted VIEW intents containing javascript: URIs.

This unsafe navigation path leads to script execution, which can result in UI spoofing or privilege escalation attacks.

The vulnerability is classified as a Cross-Site Scripting (XSS) issue and arises when an attacker uses a malicious app or adb command to send an intent with a javascript: URI, exploiting how the component handles such inputs.

Detection Guidance

The vulnerability in SailingLab AppLock 4.3.8 can be detected by checking if the BrowserMainActivity component accepts VIEW intents containing javascript: URIs, which leads to arbitrary JavaScript execution.

One way to test for this vulnerability is to use the Android Debug Bridge (adb) to send a crafted intent with a javascript: URI to the vulnerable component and observe if the script executes.

• adb shell am start -a android.intent.action.VIEW -d "javascript:alert('XSS')" com.alpha.applock/.BrowserMainActivity

If the alert or any JavaScript execution occurs, it indicates the presence of the vulnerability.

Mitigation Strategies

Immediate mitigation steps include avoiding the use of the vulnerable version 4.3.8 of SailingLab AppLock until a patch or update is available.

Restrict or monitor the use of local apps or adb commands that can send VIEW intents with javascript: URIs to the BrowserMainActivity component.

Consider uninstalling or disabling the app if it is not essential, or applying any official updates or patches provided by the vendor once released.
