Summary

WAGO: Command Injection Vulnerability in I/O-Check Service of multiple products

Notes

Summary: The reported vulnerability allows an attacker who has network access to the device to execute code with specially crafted packets.

Impact: By exploiting the described vulnerabilities the attacker potentially is able to manipulate or disrupt the device.

Mitigation: * Disable I/O-Check service * Restrict network access to the device. * Do not directly connect the device to the internet.

Remediation: The I/O-Check service protocol is only needed during installation and commissioning, not during normal operations. It is highly recommended to disable the I/O-Check service after commissioning. This is the easiest and securest way to protect your device from the listed vulnerabilities. Regardless to the action described above, the vulnerability has been fixed in FW11, released in December 2017.

CVE-2020-12522

The reported vulnerability allows an attacker who has network access to the device to execute code with specially crafted packets in WAGO Series PFC 100 (750-81xx/xxx-xxx), Series PFC 200 (750-82xx/xxx-xxx), Series Wago Touch Panel 600 Standard Line (762-4xxx), Series Wago Touch Panel 600 Advanced Line (762-5xxx), Series Wago Touch Panel 600 Marine Line (762-6xxx) with firmware versions <=FW10.

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Mitigation * Disable I/O-Check service * Restrict network access to the device. * Do not directly connect the device to the internet.

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.
