CVE-2024-25997Network attack vector

Log injection via unneutralized OCPP logging

Published Mar 12, 2024 · Updated Aug 1, 2024

Log injection in Phoenix Contact CHARX SEC-3xxx firmware 1.5.0 and earlier allows remote attackers to alter a log via OCPP messages. The OCPP logging implementation writes attacker-controlled special characters to a log file without neutralizing them, allowing forged log content. Authentication is not required; the flaw changes log integrity and can contribute to a multi-vulnerability chain that executes code as root.
