The Traveloka application 3.14.0 for Android exports com.traveloka.android.activity.common.WebViewActivity, leading to the opening of arbitrary URLs, which can inject deceptive content into the UI. (When in physical possession of the device, opening local files is also possible.) NOTE: As of 2019-09-23, the vendor has not agreed that this issue has serious impact. The vendor states that the issue is not critical because it does not allow Elevation of Privilege, Sensitive Data Leakage, or any critical unauthorized activity from a malicious user. The vendor also states that a victim must first install a malicious APK to their application.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
