Vulnerability from cvelistv5 – Published: 2021-06-25 18:25 – Updated: 2024-09-16 23:16

Title

WEIDMUELLER: WLAN devices affected by Hard-coded Credentials vulnerability

Summary

In Weidmueller Industrial WLAN devices in multiple versions an exploitable use of hard-coded credentials vulnerability exists in multiple iw_* utilities. The device operating system contains an undocumented encryption password, allowing for the creation of custom diagnostic scripts. An attacker can send diagnostic scripts while authenticated as a low privilege user to trigger this vulnerability.

Severity

8.8 (High)

Detection rules are retrieved from Rulezet.

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.
