CVE-2023-46509Public exploitNetwork attack vector

Unauthenticated code execution via texteditor.php

Published Oct 27, 2023 · Updated Sep 12, 2024

Code injection in CONTEC SolarView Compact 6.0 and earlier allows remote attackers to execute arbitrary code through texteditor.php. The public disclosure names texteditor.php as the vulnerable locus but does not identify the request parameter or the unsafe code-generation operation. No credentials or user interaction are required, and successful exploitation grants control of the embedded monitoring controller.
