CVE-2021-21787 (GCVE-0-2021-21787)

Vulnerability from cvelistv5 – Published: 2021-07-07 16:39 – Updated: 2024-08-03 18:23

Summary

A privilege escalation vulnerability exists in the way IOBit Advanced SystemCare Ultimate 14.2.0.220 driver handles Privileged I/O write requests. During IOCTL 0x9c40a0d8, the first dword passed in the input buffer is the device port to write to and the byte at offset 4 is the value to write via the OUT instruction. The OUT instruction can write one byte to the given I/O device port, potentially leading to escalated privileges of unprivileged users.

Severity ?

8.8 (High)
