An issue was discovered in KaiOS 1.0, 2.5, and 2.5.12.5. The pre-installed Email application is vulnerable to HTML and JavaScript injection attacks. An attacker can send a specially crafted email to the victim that will inject HTML into the email application’s UI as soon as the email is opened. At a bare minimum, this allows an attacker to take control over the Email application’s UI (e.g., display a malicious prompt to the user asking them to re-enter their email credentials) and also allows an attacker to abuse any of the privileges available to the mobile application.

CVE-2019-14757
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.
CVE-2019-14758
An issue was discovered in KaiOS 2.5 and 2.5.1. The pre-installed File Manager application is vulnerable to HTML and JavaScript injection attacks. An attacker can send a file via email to the victim that will inject HTML into the File Manager application (assuming the victim chooses to download the email attachment). At a bare minimum, this allows an attacker to take control over the File Manager 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.
CVE-2019-14759
An issue was discovered in KaiOS 1.0, 2.5, and 2.5.1. The pre-installed Radio application is vulnerable to HTML and JavaScript injection attacks. A local attacker can inject arbitrary HTML into the Radio application. At a bare minimum, this allows an attacker to take control over the Radio 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.
CVE-2019-14760
An issue was discovered in KaiOS 2.5. The pre-installed Recorder application is vulnerable to HTML and JavaScript injection attacks. A local attacker can inject arbitrary HTML into the Recorder application. At a bare minimum, this allows an attacker to take control over the Recorder 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.
CVE-2019-14761
An issue was discovered in KaiOS 2.5. The pre-installed Note application is vulnerable to HTML and JavaScript injection attacks. A local attacker can inject arbitrary HTML into the Note application. At a bare minimum, this allows an attacker to take control over the Note 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.
