Python proof-of-concept scripts for the MikroTrick MikroTik RouterOS SSH takeover chain (CVE-2026-67279, CVE-2026-86060, CVE-2026-67276) for authorized lab testing.
This repository contains proof-of-concept (PoC) scripts for several MikroTik RouterOS security issues researched and documented in 2026. The materials are intended for authorized security research, laboratory validation, and controlled testing only.
This project is not a production application, not a general-purpose tool, and not intended for use against systems without explicit authorization.

本仓库为 MikroTrick(MikroTik RouterOS SSH 未认证接管链) 漏洞 PoC 的中转分发镜像(英文说明见上方上游原版 README)。内容由上游公开 PoC 仓库镜像而来,仅作存档与分发用途。PoC 仅供安全研究、漏洞验证与授权测试,请勿用于未授权目标。
MikroTrick 是 CERT Polska 于 2026-09-05 披露、被在野利用的 RouterOS 未认证接管链,由两个缺陷串联:
CVE-2026-67279(CWE-841):SSH 在用户认证前接受客户端 rekey,会话被错误推进到连接协议阶段——未认证客户端即可打开 session channel 并发送 exec 请求;
CVE-2026-86060(CWE-88):SSH 登录路径参数注入。以禁用字符开头的用户名(观测到 -2)被登录 helper 当作"从文件描述符读取受信任身份"的语法,从而把会话策略掩码替换为完整管理员权限。
受影响版本:[7.24, 7.24.2)、[7.0.0, 7.23.4)、[6.0.0, 6.49.21)
修复版本:7.24.2(Stable)/ 7.23.4(Long-term)/ 6.49.21(Long-term)/ 7.25beta3
利用前提:SSH 端口可达(默认配置不开放;暴露的多为管理员手动放开)
在野利用:已确认(自 2026-09-02 起);已入 CISA KEV
