Admin access via unprotected configuration files
Published Jul 11, 2023 · Updated Nov 12, 2024
Improper access control in Siemens SIMATIC CN 4100 before V2.5 allows remote authenticated users to gain admin access via configuration files. The device applies insufficient authorization checks to configuration-file access, allowing a lower-privileged network user to reach administrative settings. Successful exploitation grants administrator privileges and can provide complete device control; the Siemens advisory requires network reachability and a low-privilege account.
