Vulnerability from github – Published: 2022-05-24 17:44 – Updated: 2022-10-20 12:00

Details

A vulnerability has been identified in RUGGEDCOM RM1224 (All versions >= V4.3), SCALANCE M-800 (All versions >= V4.3), SCALANCE S615 (All versions >= V4.3), SCALANCE SC-600 Family (All versions >= V2.0 and < V2.1.3), SCALANCE X300WG (All versions < V4.1), SCALANCE XM400 (All versions < V6.2), SCALANCE XR500 (All versions < V6.2), SCALANCE Xx200 Family (All versions < V4.1). Affected devices contain a stack-based buffer overflow vulnerability in the handling of STP BPDU frames that could allow a remote attacker to trigger a denial-of-service condition or potentially remote code execution. Successful exploitation requires the passive listening feature of the device to be active.

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.
