![]() Subsequently, CyberArk researchers also explored the possibility of creating a new folder in "C:\ProgramData" before a privileged process is executed. In one case, it was observed that two different processes - one privileged and the other run as an authenticated local user - shared the same log file, potentially allowing an attacker to exploit the privileged process to delete the file and create a symbolic link that would point to any desired arbitrary file with malicious content. McAfee Endpoint Security and McAfee Total ProtectionĬheck Point ZoneAlarm and Check Point Endpoint SecurityĬVE-2019-19688, CVE-2019-19689, and three more unassigned flaws Given that every user has both write and delete permission on the base level of the directory, it raises the likelihood of a privilege escalation when a non-privileged process creates a new folder in "ProgramData" that could be later accessed by a privileged process. ![]() Per CyberArk, the bugs result from default DACLs (short for Discretionary Access Control Lists) for the "C:\ProgramData" folder of Windows, which are by applications to store data for standard users without requiring additional permissions. Chief among the flaws is the ability to delete files from arbitrary locations, allowing the attacker to delete any file in the system, as well as a file corruption vulnerability that permits a bad actor to eliminate the content of any file in the system.
