Local privilege escalation in Siemens SINEC INS via cap_dac_override capability
CVE-2026-46748 affects Siemens SINEC INS in all versions earlier than V1.0 SP2 Update 6. The vulnerability is caused by an affected binary being configured with the Linux capability cap_dac_override. That capability permits the process to bypass normal file system permission checks, which can lead to unrestricted access to the file system. In practice, this creates a local privilege escalation condition in which a local attacker can abuse the over-privileged binary to perform arbitrary file modification and ultimately obtain root privileges on the affected system.
