Description

CERT Polska has received a report about vulnerabilities in Kioware for Windows software and participated in coordination of their disclosure.

The vulnerability CVE-2024-3459 in KioWare for Windows (all versions through 8.34) allows to escape the environment by downloading PDF files, which then by default are opened in an external PDF viewer. By using built-in functions of that viewer it is possible to launch a web browser, search through local files and, subsequently, launch any program with user privileges.

The vulnerability CVE-2024-3460 in KioWare for Windows (all versions through 8.34) allows to exit the software and use other already opened applications utilizing a short time window before the forced automatic logout occurs. Then, by using some built-in function of these applications, one may launch any other programs.  In order to exploit this vulnerability external applications must be left running when the KioWare software is launched. Additionally, an attacker must know the PIN (see CVE-2024-3461) set for this Kioware instance and also slow down the application with some specific task which extends the usable time window.

The vulnerability CVE-2024-3461 in KioWare for Windows (all version through 8.35) allows to brute force the PIN number, which protects the application from being closed, as there are no mechanisms preventing a user from excessively guessing the number.
