Title

Dell EMC iDRAC不安全文件权限漏洞

Description

Dell EMC iDRAC Service Module（iSM）是美国戴尔（Dell）公司的一套运行在服务器上的轻量级软件。该软件能够将集成Dell EMC远程访问控制器（iDRAC）扩展到主机操作系统。基于Linux和XenServer平台的Dell EMC iSM中存在安全漏洞，该漏洞源于在启动时程序将主机操作系统(/etc/hosts)的主机文件的默认文件权限更改成全局可写入。攻击者可利用该漏洞修改主机文件并可能将流量重定向到托管有恶意内容的网站。

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.
