Summary
CVE-2020-37064 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Epson (inferred from references). Its CVSS base score is 8.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception by Unquoted Path (T1574.009); ranked at the 4.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 CM-6 (Configuration Settings) and RA-5 (Vulnerability Monitoring and Scanning).
Deeper analysis
CVE-2020-37064 is an unquoted service path vulnerability in the EMP_NSWLSV service of EPSON EasyMP Network Projection version 2.81. The issue arises from an unquoted path at C:\Program Files (x86)\EPSON Projector\EasyMP Network Projection V2\, enabling local users to potentially execute arbitrary code. It carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-428.
Local users with low privileges can exploit this vulnerability by placing a malicious executable in a directory that the Windows service loader traverses before reaching the legitimate binary, due to the unquoted path. Successful exploitation allows the attacker's code to run with LocalSystem privileges, granting high-impact confidentiality, integrity, and availability effects without requiring user interaction.
Epson provides support and a patched version, EasyMP Network Projection v2.86 for Windows, at their official site. Additional details on the vulnerability and exploitation are available in the VulnCheck advisory and a proof-of-concept exploit published on Exploit-DB (ID 48069).
A public exploit on Exploit-DB demonstrates practical exploitability, highlighting risks in environments running the affected software.
