Title

MikroTik RouterOS缓冲区溢出漏洞

Description

MikroTik RouterOS是MikroTik公司基于Linux内核开发的一种路由操作系统，通过安装该系统可将标准的x86 PC设备变成专业路由器。 MikroTik RouterOS 6.41.3及之前版本存在缓冲区溢出漏洞。该漏洞源于MikroTik RouterOS在处理NetBIOS会话请求时，它的SMB服务中会出现缓冲区溢出问题。由于溢出问题发生在身份验证之前，因此未经身份验证的远程攻击者可以利用此漏洞获取该系统的代码执行权限。

CVE-2018-7445 (GCVE-0-2018-7445)

Vulnerability from cvelistv5 – Published: 2018-03-19 21:00 – Updated: 2025-10-21 23:45

Summary

A buffer overflow was found in the MikroTik RouterOS SMB service when processing NetBIOS session request messages. Remote attackers with access to the service can exploit this vulnerability and gain code execution on the system. The overflow occurs before authentication takes place, so it is possible for an unauthenticated remote attacker to exploit it. All architectures and all devices running RouterOS before versions 6.41.3/6.42rc27 are vulnerable.

Severity

9.8 (Critical)

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.
