Siemens Industrial产品拒绝服务漏洞（CNVD-2022-87983）
Description
SIMATIC Drive Controllers用于生产机器的自动化，结合了SIMATIC S7-1500 CPU和SINAMICS S120驱动控制的功能。SIMATIC ET 200SP Open Controller是SIMATIC S7-1500控制器的基于PC的版本，包括可选的可视化功能以及紧凑型设备中的中央I/O。SIMATIC S7-1200 CPU产品专为工业环境中的离散和连续控制而设计，如全球制造业、食品和饮料以及化工行业。SIMATIC S7-1500 CPU产品专为全球制造、食品和饮料以及化工等工业环境中的离散和连续控制而设计。SIMATIC S7-1500 Software Controller是用于基于PC的自动化解决方案的SIMATIC软件控制器。SIMATIC S7-PLCSIM Advanced模拟S7-1200、S7-1500和其他一些PLC衍生产品。包括模拟PLC的完全网络访问，即使在虚拟化环境中也是如此。SIPLUS extreme产品设计用于在极端条件下可靠运行，基于SIMATIC,LOGO!,SITOP,SINAMICS,SIMOTION,SCALANCE或其他设备。SIPLUS设备使用与其所基于的产品相同的固件。TIM 1531 IRC是SIMATIC S7-1500、S7-400、S7-300与SINAUT ST7、DNP3和IEC 60870-5-101/104的通信模块，具有三个RJ45接口，用于通过基于IP的网络（WAN/LAN）进行通信，以及一个RS 232/RS 485接口，用于经经典WAN网络进行通信。
Siemens Industrial产品存在拒绝服务漏洞，该漏洞是由于受影响的设备无法正确处理发送到端口102/tcp的某些特制数据包，攻击者可利用该漏洞在设备中拒绝服务。

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.
