Summary

CVE-2020-37058 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Andreaelectronics (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 2.2th 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 SI-2 (Flaw Remediation).

Deeper analysis

CVE-2020-37058 is an unquoted service path vulnerability in the Windows service configuration of Andrea ST Filters Service version 1.0.64.7. This flaw, classified under CWE-428, occurs when the service binary path lacks proper quotation, enabling unintended executable resolution during service startup.

Local attackers with low privileges can exploit this vulnerability by placing a malicious executable in a directory that the service search path traverses before reaching the legitimate binary. When the service starts, the injected code executes with elevated LocalSystem privileges, granting high confidentiality, integrity, and availability impact as reflected in its CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

T1574.009 Path Interception by Unquoted Path Stealth
Adversaries may execute their own malicious payloads by hijacking vulnerable file path references.
Why these techniques?

Directly enables path interception via unquoted service binary path (CWE-428), allowing low-priv local attacker to hijack execution flow with LocalSystem privileges on service start.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Requires identification, reporting, and correction of the specific unquoted service path flaw in Andrea ST Filters Service to prevent exploitation.

prevent

Establishes and enforces secure configuration settings for Windows services, including quoted executable paths and restricted write access to search path directories.

prevent

Applies least privilege to service accounts, limiting the damage from malicious code execution even if the unquoted path is exploited.
