CVE-2024-28750Network attack vector

Authenticated command injection via file deletion function

Published Jul 9, 2024 · Updated Aug 2, 2024

OS command injection in ifm Smart PLC AC14xx and AC4xxS firmware 4.3.17 and earlier allows remote authenticated users to execute commands. The file-deletion function passes attacker-controlled input into an operating-system command without neutralizing command syntax. High-privilege access to the network interface is required, and successful exploitation permits arbitrary command execution on the controller.
