Vulnerability from csaf_wagogmbhcokg - Published: 2026-10-01 10:00 - Updated: 2026-10-01 10:00Summary
WAGO: Multiple Devices are affected by a Vulnerability in BACnet IP Stack
Severity
Critical
Notes
Summary: Multiple WAGO devices are affected by a vulnerability in the dynamic creation of BACnet File Objects. The object name is used as a file path without sufficient validation and is not restricted to the intended directory, so relative paths can be used to reach files elsewhere in the file system.
Impact: An attacker can read or overwrite arbitrary files without authentication via BACnet File Object indirect addressing. This may expose sensitive data (e.g., password files) and enable full system compromise or service disruption.
Remediation: Update to Firmware version 4.8.9 (FW30) or higher. For the latest custom Firmware please contact the WAGO support.
Disclaimer: WAGO controllers must never be exposed directly to the Internet without additional security measures such as firewalls, VPNs and proper network segmentation. BACnet/IP is not a secure protocol because it lacks encryption and authentication which makes systems vulnerable to unauthorized access and manipulation
The object name of a dynamically created BACnet File Object is interpreted as a file path without sufficient validation. Because relative paths are not limited to the intended directory, an unauthenticated remote attacker can traverse outside of it and read or overwrite arbitrary files on the device, which may lead to full system compromise.
9.8 (Critical)
Vendor Fix
Update to Firmware version 4.8.9 (FW30) or higher. For the latest custom Firmware please contact the WAGO support.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
