CVE-2026-25573

Local command execution via unquoted socket values

Published Mar 10, 2026 · Updated Mar 10, 2026

Command injection in Siemens SICAM SIAPP SDK before 2.1.7 allows local users to execute commands through caller-controlled socket values. The edgedata_ipc_unix_server_listen() helper interpolates user and UNIX-socket path strings into chown and chmod command lines passed to system(). Exploitation requires a downstream application to pass untrusted user or channel_name data into the API; successful injection executes with the application's privileges and can compromise its host environment.
