CVE-2023-23333Public exploitNetwork attack vector

Unauthenticated command execution via downloader.php file parameter

Published Feb 6, 2023 · Updated Mar 26, 2025

OS command injection in Contec SolarView Compact before 7.21 allows remote attackers to execute commands through the download interface. The downloader.php handler inadequately validates the file query parameter before incorporating it into an OS command, so shell metacharacters append attacker-controlled commands. No authentication or user interaction is required; injected commands run with the web server's privileges and can read or alter data or destroy the system.
