AI-suggested
In the absence of official patches, administrators should restrict local user permissions to the minimum necessary, enforce application whitelisting to prevent execution of unauthorized files, and deploy endpoint detection and response (EDR) solutions to identify suspicious privilege escalation attempts. Regular auditing of user privileges and system logs can help detect early signs of exploitation. Network segmentation and the use of least privilege principles for local accounts can limit the impact of a successful attack. Additionally, educating users about the risks of executing untrusted files and implementing strict software installation policies will reduce the likelihood of exploitation.
Description
NAVER MYBOX Explorer for Windows before 3.0.8.133 allows a local attacker to escalate privileges to NT AUTHORITY\SYSTEM by executing arbitrary files due to improper privilege checks.
