Description
A vulnerability exits in driver snxppamd.sys in SUNIX Parallel Driver x64 - 10.1.0.0, which allows low-privileged users to read and write arbitary i/o port via specially crafted IOCTL requests . This can be exploited for privilege escalation, code execution under high privileges, and information disclosure. These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious code.
