This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
Vulnerability related to an unquoted service path in Small HTTP Server 3.06.36, specifically affecting the executable located at 'C:\Program Files (x86)\shttps_mg\http.exe service'. This misconfiguration allows a local attacker to place a malicious executable with the same name in a higher priority directory, causing the service to execute the malicious file instead of the legitimate one. Exploiting this flaw could allow arbitrary code execution, unauthorized access to the system, or service disruption. To mitigate the risk, the service path must be properly quoted, and systems must be kept up to date with security patches, while restricting physical and network access.
Remediation
Check the references section for vendor advisories and patches from smallsrv. Update small_http_server to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
