Descriptions

An issue was discovered in SoftMaker Office 2024 / NX before revision 1214 and SoftMaker FreeOffice 2014 before revision 1215. FreeOffice 2021 is also affected, but won't be fixed.





The SoftMaker Office and FreeOffice MSI installer files were found to
produce a visible conhost.exe window running as the SYSTEM user when
using the repair function of msiexec.exe. This allows a local,
low-privileged attacker to use a chain of actions, to open a fully
functional cmd.exe with the privileges of the SYSTEM user.

Se descubrió que los archivos de instalación de SoftMaker Office y FreeOffice MSI producían una ventana visible de conhost.exe ejecutándose como el usuario de SYSTEM cuando se utiliza la función de reparación de msiexec.exe.Esto permite a un atacante local con pocos privilegios utilizar una cadena de acciones para abrir un cmd.exe completamente funcional con los privilegios del usuario de SYSTEM.
