CVE-2019-14757: Kaiostech Kaios

Medium severity, CVSS 6.1. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Kaiostech Kaios: version 2.5 only; version 2.5.1 only
