CVE-2025-5243Network attack vector

Unauthenticated code execution via dangerous file upload

Published Jul 24, 2025 · Updated Jun 5, 2026

Unrestricted file upload in SMG Software Information Portal before 13.06.2025 allows remote attackers to execute code without authentication. The portal accepts a dangerous file type for server-side inclusion or execution, including as a web shell, but the public record does not identify the affected upload endpoint. No credentials or user interaction are required, and successful exploitation runs attacker-supplied code in the web server's execution context.
