CVE-2023-47253Public exploitNetwork attack vector

Unauthenticated code execution via PHP injection

Published Nov 6, 2023 · Updated Jun 12, 2025

Command injection in Qualitor Software Qualitor 8.20 and earlier allows remote attackers to execute arbitrary PHP code via gridValoresPopHidden. The processVariavel.php endpoint interprets attacker-supplied parameter content as PHP code instead of treating it as data. No authentication or user interaction is required, and successful exploitation executes arbitrary commands on the affected server.
