GIGABYTE Multiple Products Privilege Escalation
CVE-2018-19323 is a critical-severity vulnerability in Aorus Graphics Engine from Gigabyte, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.57 as the first without the flaw, so updating Aorus Graphics Engine to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on October 24, 2022, which means attacks have been observed in the wild, including in ransomware campaigns.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update Aorus Graphics Engine to 1.57 or a later version.
- Update Xtreme Gaming Engine to 1.26 or a later version.
- CISA's required action: Apply updates per vendor instructions.
- Read the advisory on gigabyte.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
