> Authenticated remote attacker can read arbitrary files as root via JSON-RPC interface in Ruggedcom Rox; update to v2.17.1.

Siemens Ruggedcom Rox industrial network devices contain an improper access control vulnerability (CVE-2025-40948) in the web server's JSON-RPC interface that allows an authenticated remote attacker to read arbitrary files from the underlying operating system filesystem with root privileges. The vulnerability affects multiple Ruggedcom Rox models including MX5000, RX1400 through RX1536 series, and RX5000, all versions prior to 2.17.1. Siemens has released fixed versions and recommends immediate patching. The article does not indicate active exploitation in the wild. Defenders should prioritize updating affected devices and implementing network segmentation to restrict access to these industrial control devices, particularly in critical manufacturing environments where Ruggedcom Rox is widely deployed globally.
