CVE-2020-37062
Published: 01 February 2026
Summary
CVE-2020-37062 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Weird Solutions (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 AC-6 (Least Privilege) and CM-6 (Configuration Settings).
Deeper analysis
CVE-2020-37062 is an unquoted service path vulnerability in DHCP Turbo version 4.61298. The issue stems from the service binary path not being properly quoted, which affects the Windows service execution process for this DHCP server software. It is classified under CWE-428 (Unquoted Search Path or Element) and 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).
Local attackers with low privileges can exploit this vulnerability by placing malicious executables in directories along the service's search path. When the DHCP Turbo service starts or restarts, the system may execute the attacker's binary instead of the legitimate one, allowing arbitrary code execution and privilege escalation to the service's elevated context.
Advisories and proof-of-concept exploits are documented in referenced sources, including Exploit-DB at https://www.exploit-db.com/exploits/48080 and VulnCheck at https://www.vulncheck.com/advisories/dhcp-turbo-dhcp-turbo-unquoted-service-path, with the vendor site at https://www.weird-solutions.com. These resources provide further details on exploitation and potential mitigations such as correcting the service path quoting or restricting access to service directories.

Why these techniques?
Unquoted service path (CWE-428) directly enables path interception by placing a malicious executable in a higher directory of the service binary path, executed on service start for privilege escalation.

Directly remediates the unquoted service path flaw in DHCP Turbo by identifying, reporting, and applying patches or configuration fixes to prevent privilege escalation.
Enforces secure baseline configuration settings for the service, including proper quoting of the executable path and restrictive permissions on search path directories to block exploitation.
Applies least privilege to prevent low-privileged local attackers from writing malicious executables to directories traversed by the unquoted DHCP Turbo service path.
