Title

Siemens SCALANCE和RuggedCmd设备堆栈溢出漏洞

Description

SCALANCE SC-600设备（SC622-2C、SC632-2C、SC636-2C、SC642-2C、SC646-2C）用于保护受信任的工业网络免受不受信任的网络的攻击。SCALANCE M-800/S615工业路由器用于通过mobilenetworks（例如GPRS或UMTS）对工厂进行安全远程访问，具有防火墙的集成安全功能，可防止未经授权的访问，VPN可保护数据传输。SCALANCE X开关用于连接工业组件，如可编程逻辑控制器（PLC）或人机接口（HMI）。RUGGEDCOM RM1224是一个4G路由器，用于通过LTE（4G）-移动无线电从基于以太网的设备进行无线IP通信。 Siemens SCALANCE和RuggedCmd设备存在堆栈溢出漏洞。远程攻击者可利用漏洞触发拒绝服务条件或远程代码执行。

CVE-2021-25667 (GCVE-0-2021-25667)

Vulnerability from cvelistv5 – Published: 2021-03-15 17:03 – Updated: 2026-06-02 19:24

Summary

A vulnerability has been identified in RUGGEDCOM RM1224 (All versions >= V4.3 and < V6.4), SCALANCE M-800 (All versions >= V4.3 and < V6.4), SCALANCE S615 (All versions >= V4.3 and < V6.4), SCALANCE SC-600 Family (All versions >= V2.0 and < V2.1.3), SCALANCE XB-200 (All versions < V4.1), SCALANCE XC-200 (All versions < V4.1), SCALANCE XF-200BA (All versions < V4.1), SCALANCE XM400 (All versions < V6.2), SCALANCE XP-200 (All versions < V4.1), SCALANCE XR-300WG (All versions < V4.1), SCALANCE XR500 (All versions < V6.2). 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.

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.
