What is CVE-2023-7270?
CVE-2023-7270 is a medium-severity vulnerability in SoftMaker Software GmbH FreeOffice, published on 27 Jun 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
