Information has been disclosed about a new high criticality vulnerability that affects the Apple iTunes software in Windows environments. This vulnerability would allow an attacker who had access as a non-privileged user on a machine to escalate privileges to local administrator.
This vulnerability is caused by incorrectly setting permissions on one of the folders created during the installation of the software:
C:\ProgramData\Apple Computer\iTunes\SC Info
This folder would have write permissions for any user, so an unprivileged user could delete it, and create a symbolic link pointing to any system folder such as c:Windows.
Subsequently, using the repair function of the installation binary, the rewriting of certain files could be forced, allowing privileges to be escalated up to SYSTEM access.
This vulnerability has been discovered by The Synopsys Cybersecurity Research Center (CyRC).
