Iobit: >> Advanced Systemcare Security Vulnerabilities
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]

The AscRegistryFilter.sys kernel driver in IObit Advanced SystemCare 13.2 allows an unprivileged user to send an IOCTL to the device driver. If the user provides a NULL entry for the dwIoControlCode parameter, a kernel panic (aka BSOD) follows. The IOCTL codes can be found in the dispatch function: 0x8001E000, 0x8001E004, 0x8001E008, 0x8001E00C, 0x8001E010, 0x8001E014, 0x8001E020, 0x8001E024, 0x8001E040, 0x8001E044, and 0x8001E048. \DosDevices\AscRegistryFilter and \Device\AscRegistryFilter are affected.

IObit Advanced SystemCare, which includes Monitor_win10_x64.sys or Monitor_win7_x64.sys, 1.2.0.5 (and possibly earlier versions) allows a user to send an IOCTL (0x9C402088) with a buffer containing user defined content. The driver's subroutine will execute a wrmsr instruction with the user's buffer for input.
