HTML and JavaScript Injection Vulnerability in KaiOS Contacts Application

CVE-2019-14757 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

An issue was discovered in KaiOS 2.5 and 2.5.1. The pre-installed Contacts application is vulnerable to HTML and JavaScript injection attacks. An attacker can send a vCard file to the victim that will inject HTML into the Contacts application (assuming the victim chooses to import the file). At a bare minimum, this allows an attacker to take control over the Contacts application's UI (e.g., display a malicious prompt to the user asking them to re-enter credentials such as their KaiOS credentials to continue using the application) and also allows an attacker to abuse any of the privileges available to the mobile application.
