Technical details

A privilege escalation vulnerability exists in NAVER MYBOX Explorer for Windows due to incorrect privilege assignment (CWE-266). The application fails to properly validate or restrict access to specific registry keys used by its service or background processes. A local attacker with low-level user privileges can manipulate these registry entries to redirect application execution or configuration. This allows the attacker to execute arbitrary code with NT AUTHORITY\SYSTEM privileges. The issue is resolved in version 3.0.11.160.
