Allele Security Alert
ASA-2018-00010, CVE-2018-10712, CORE-2018-0005
Drivers allow non-privileged user arbitrary access to I/O ports
The vulnerability described in this alert affects the drivers AsrDrv101.sys and AsrDrv102.sys. They are installed by the following ASRock utilities:
ASRock RGBLED before v18.104.22.168
A-Tuning before v3.0.210
F-Stream before v3.0.210
RestartToUEFI before v22.214.171.124
ASRock RGBLED v1.0.36
Proof of concept
The drivers affected expose to a non-privileged user arbitrary access to I/O ports through ioctl() system call. The ioctl arguments are 0x222810 and 0x222814.
Access to I/O ports allow an attacker to directly tinker with the system and take advantage in several ways. This vulnerability allows an attacker to achieve privilege escalation, information leakage, denial of service and not limited to bypassing of mitigations and protections imposed by operating system.
