CVE-2020-37064 in EasyMP Network Projection
Summary
by MITRE • 02/01/2026
EPSON EasyMP Network Projection 2.81 contains an unquoted service path vulnerability in the EMP_NSWLSV service that allows local users to potentially execute arbitrary code. Attackers can exploit the unquoted path in C:\Program Files (x86)\EPSON Projector\EasyMP Network Projection V2\ to inject malicious code that would execute with LocalSystem privileges.

The vulnerability identified as CVE-2020-37064 affects EPSON EasyMP Network Projection version 2.81 and represents a critical security flaw stemming from an unquoted service path configuration. This issue specifically impacts the EMP_NSWLSV service component within the EPSON projector software suite, creating a privilege escalation vector that could allow local attackers to execute malicious code with elevated LocalSystem privileges. The vulnerability arises from improper service path handling where the Windows service configuration does not properly quote the executable path, creating opportunities for path traversal attacks.
The technical implementation of this vulnerability resides in the service installation process where the path to the executable file lacks proper quotation marks around directory names containing spaces. When Windows attempts to locate and execute the service binary, it follows a path resolution mechanism that can be manipulated by placing malicious executables in directories leading up to the target path. The vulnerable path C:\Program Files (x86)\EPSON Projector\EasyMP Network Projection V2\ contains spaces that are not properly quoted in the service configuration, allowing attackers to place malicious binaries in parent directories where the system will execute them instead of the legitimate service binary. This represents a classic Windows service path vulnerability that aligns with CWE-428, which addresses unquoted service paths in Windows environments.
The operational impact of this vulnerability extends beyond simple code execution capabilities as it provides a pathway for attackers to gain system-level privileges without requiring authentication. Local users who can access the system can exploit this weakness to inject malicious code that will execute with LocalSystem privileges, effectively granting them complete control over the affected system. This creates a significant risk for environments where EPSON projector systems are deployed, particularly in corporate settings where these devices might be accessible to multiple users or where physical access to the devices is possible. The vulnerability essentially transforms a local user account into a system administrator-level attacker, bypassing normal access controls and privilege boundaries.
Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, specifically mapping it to techniques involving privilege escalation and persistence. The unquoted service path vulnerability falls under the category of service execution manipulation where attackers can leverage the system's path resolution behavior to achieve unauthorized code execution. Organizations should implement comprehensive patch management procedures to address this vulnerability immediately, as the exploitation requires minimal technical skill and can be automated. The remediation approach involves either patching the software to properly quote the service paths or manually correcting the service configuration to ensure proper path handling. Additionally, system administrators should conduct thorough service path audits across all installed software to identify similar vulnerabilities in other applications, as this type of flaw commonly affects poorly configured Windows services and represents a persistent threat vector in enterprise environments.
