Summary
Cryptomator version 1.9.2 allows local privilege escalation for low privileged users via the `repair` function in the MSI installer. The issue arises from the MSI's repair function spawning a SYSTEM Powershell without the `-NoProfile` parameter, leading to the loading of the user's profile.
Risk Assessment
Organizations may be exposed to unauthorized access to the system, potentially leading to serious security breaches. Low privileged users could gain access to elevated privileges.
Recommendation
It is recommended to upgrade to version 1.9.3, which contains a fix for this issue. Alternatively, adding the `-NoProfile` parameter to the spawned Powershell can serve as a temporary workaround.
Original NVD description (English source)
Cryptomator encrypts data being stored on cloud infrastructure. The MSI installer provided on the homepage for Cryptomator version 1.9.2 allows local privilege escalation for low privileged users, via the `repair` function. The problem occurs as the repair function of the MSI is spawning an SYSTEM Powershell without the `-NoProfile` parameter. Therefore the profile of the user starting the repair will be loaded. Version 1.9.3 contains a fix for this issue. Adding a `-NoProfile` to the powershell is a possible workaround.
