Title

Siemens SIMATIC PCS 7和SIMATIC WinCC路径遍历漏洞

Description

Siemens SIMATIC PCS 7和SIMATIC WinCC都是德国西门子（Siemens）公司的产品。SIMATIC PCS 7是一套过程控制系统。SIMATIC WinCC是一套自动化的数据采集与监控（SCADA）系统。 Siemens SIMATIC PCS 7和SIMATIC WinCC存在路径遍历漏洞，该漏洞源于下载文件时系统无法正确中和路径名中的特殊元素。攻击者随后可利用漏洞导致路径名解析到服务器上受限目录之外的位置，并读取意外的关键文件。

Summary

A vulnerability has been identified in OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions < V9.0 Upd4), OpenPCS 7 V9.1 (All versions), SIMATIC BATCH V8.2 (All versions), SIMATIC BATCH V9.0 (All versions), SIMATIC BATCH V9.1 (All versions), SIMATIC NET PC Software V14 (All versions), SIMATIC NET PC Software V15 (All versions), SIMATIC NET PC Software V16 (All versions < V16 Update 6), SIMATIC NET PC Software V17 (All versions < V17 SP1), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC04), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions), SIMATIC Route Control V9.1 (All versions), SIMATIC WinCC V15 and earlier (All versions < V15 SP1 Update 7), SIMATIC WinCC V16 (All versions < V16 Update 5), SIMATIC WinCC V17 (All versions < V17 Update 2), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 5). When downloading files, the affected systems do not properly neutralize special elements within the pathname. An attacker could then cause the pathname to resolve to a location outside of the restricted directory on the server and read unexpected critical files.

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.
