CVE-2018-20621 describes a local privilege escalation vulnerability in Microvirt MEmu 6.0.6, specifically within the MemuService.exe service binary. Insecure permissions during installation allow an attacker to perform binary planting, enabling arbitrary code execution with NT AUTHORITY/SYSTEM privileges. This high-severity vulnerability (CVSS 7.8) has a low attack complexity and requires local access, but can lead to complete compromise of confidentiality, integrity, and availability. While no public exploits are currently available in Metasploit or ExploitDB, and there is minimal community discussion, the potential for a high impact necessitates awareness.
