CVE-2025-41359 PUBLISHED

Multiple vulnerabilities in Small HTTP server by Smallsrv

Assigner: INCIBE
Reserved: 16.04.2025 Published: 26.03.2026 Updated: 26.03.2026

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.
