CVE-2025-41769 is a critical buffer overflow vulnerability in the PROFINET service of multiple Phoenix Contact industrial devices. The flaw is present in the default configuration and can be triggered remotely by sending crafted PROFINET packets to a vulnerable device. The issue affects multiple Phoenix Contact product lines, including AXC F, RFC, BPC, EPC, PLCnext Control, and VL3 UPC devices, in firmware versions starting at 2019.0.4 and including versions earlier than 2026.0.3. Because the vulnerable service is exposed as part of normal PROFINET functionality, exploitation does not require authentication or user interaction.
