IOBit Advanced System Care (Asc.exe) 15 and Action Download Center both download components of IOBit suite into ProgramData folder, ProgramData folder has "rwx" permissions for unprivileged users. Low privilege users can use SetOpLock to wait for CreateProcess and switch the genuine component with a malicious executable thus gaining code execution as a high privilege user (Low Privilege -> high integrity ADMIN).

A Use after Free vulnerability exists in IOBit Advanced SystemCare 15 pro via requests sent in sequential order using the IOCTL driver codes, which could let a malicious user execute arbitrary code or a Denial of Service (system crash). IOCTL list: iobit_ioctl = [0x8001e01c, 0x8001e020, 0x8001e024, 0x8001e040,0x8001e044, 0x8001e048, 0x8001e04c, 0x8001e000, 0x8001e004, 0x8001e008, 0x8001e00c, 0x8001e010, 0x8001e014, 0x8001e018]

An information disclosure vulnerability exists in the the way IOBit Advanced SystemCare Ultimate 14.2.0.220 driver handles Privileged I/O read requests. A specially crafted I/O request packet (IRP) can lead to privileged reads in the context of a driver which can result in sensitive information disclosure from the kernel. The IN instruction can read two bytes from the given I/O device, potentially leaking sensitive device data to unprivileged users.

An information disclosure vulnerability exists in the IOCTL 0x9c40a148 handling of IOBit Advanced SystemCare Ultimate 14.2.0.220. A specially crafted I/O request packet (IRP) can lead to a disclosure of sensitive information. An attacker can send a malicious IRP to trigger this vulnerability.
