The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read/write data from/to I/O ports. This vulnerability allows attackers to run code with elevated privileges. With a CVSS score of 7.8, this vulnerability is classified as high severity, representing a serious risk to organizations using affected products.
Risk to organizations includes potential unauthorized access to sensitive data and system control. Given the local attack vector and low complexity, exploitation could be executed with minimal skills. Organizations should prioritize patching immediately to mitigate this vulnerability.
The GIGABYTE vulnerability was first published on December 21, 2018, and has been analyzed for its impact on various products. The vulnerability was added to the Known Exploited Vulnerabilities Catalog on October 24, 2022, indicating its active exploitation status.
Given the potential risks associated with this vulnerability, organizations must take immediate action to apply vendor-recommended updates and ensure system security.
Vulnerability Details
The vulnerability identified as CVE-2018-19322 is associated with the GIGABYTE APP Center and its drivers that allow unauthorized I/O access. The CVSS score of 7.8 indicates a high severity with significant impacts on confidentiality, integrity, and availability.
Affected products include GIGABYTE APP Center, AORUS GRAPHICS ENGINE, OC GURU II, and XTREME GAMING ENGINE. The vulnerability is categorized under CWE-749, indicating improper privilege management.
Technical Analysis
The root cause of this vulnerability lies in the design of the GPCIDrv and GDrv low-level drivers, which improperly handle I/O operations. Attackers may exploit this flaw by running malicious code that interacts with the I/O ports, potentially gaining elevated privileges.
The attack vector is local, requiring physical access to the machine. The attack complexity is low, meaning that even a skilled attacker could exploit this vulnerability with minimal effort. The required privileges are low, allowing an attacker with standard user rights to exploit the system.
User interaction is not required to exploit this vulnerability, and it significantly impacts confidentiality, integrity, and availability, with high potential damage to organizational systems.
Risk & Impact Analysis
Real-world deployment of vulnerable GIGABYTE products increases the risk of unauthorized access and control over systems. This vulnerability poses a significant threat to organizations, with the potential for data exfiltration and system manipulation.
The urgency for remediation is high, as the vulnerability is actively exploited. Organizations must prioritize immediate patching to avoid severe repercussions.
