CVE-2022-22262 in Live Service
Summary
by MITRE • 03/01/2022
ROG Live Service’s function for deleting temp files created by installation has an improper link resolution before file access vulnerability. Since this function does not validate the path before deletion, an unauthenticated local attacker can create an unexpected symbolic link to system file path, to delete arbitrary system files and disrupt system service.

The vulnerability identified as CVE-2022-22262 affects ROG Live Service, a component developed by ASUS for managing gaming laptop services and updates. This flaw resides within the service's temporary file cleanup mechanism, specifically in how it handles file path resolution during deletion operations. The issue represents a classic improper link resolution vulnerability that allows attackers to manipulate the system's file deletion process through symbolic link manipulation. The root cause stems from inadequate path validation within the file deletion function, which fails to properly verify the legitimacy of file paths before executing deletion operations.
This vulnerability falls under CWE-367, which describes the dangerous use of a function that can be manipulated to access unintended resources, and aligns with ATT&CK technique T1059.001 for command and scripting interpreter usage. The improper link resolution creates a privilege escalation path where local attackers can leverage the service's file deletion capabilities to target system-critical files. Attackers exploit this by creating symbolic links in strategic locations that point to system files, then trigger the deletion function to remove these targeted files. The impact extends beyond simple file deletion, as the attacker can potentially disrupt system services, compromise system stability, or even create persistent access points.
The operational impact of CVE-2022-22262 is significant for affected systems, particularly in enterprise environments where gaming laptops or desktops running ASUS software are prevalent. Attackers can leverage this vulnerability to delete critical system files, modify system configurations, or disable essential services that maintain system integrity. The vulnerability is particularly concerning because it requires no authentication, making it accessible to any local user with basic system access. This creates a vector for both casual attackers seeking to disrupt services and more sophisticated threat actors looking to establish persistent access or cause system-wide disruptions.
Mitigation strategies for this vulnerability should focus on immediate patching of the ROG Live Service component, as provided by ASUS security updates. System administrators should also implement strict file system permissions and monitor for unauthorized symbolic link creation in temporary directories. The principle of least privilege should be enforced, limiting the service's access to only necessary file paths and ensuring proper path validation mechanisms are in place. Additionally, network segmentation and endpoint protection solutions should be configured to detect suspicious file deletion activities and symbolic link creation patterns. Organizations should conduct thorough vulnerability assessments to identify systems running affected versions of ROG Live Service and ensure comprehensive monitoring of system file integrity to detect potential exploitation attempts.
