## Summary

Recent research has uncovered significant vulnerabilities in the baseboard management controllers (BMCs) of thousands of servers produced by major manufacturers. These flaws, some of which have been present for over a decade, enable attackers to exploit the BMCs to execute malicious code remotely, potentially allowing for persistent access to critical datacenter resources. The implications of these vulnerabilities are severe, as they could lead to unauthorized control over server operations and sensitive data breaches.

## Key takeaways

- Thousands of servers are at risk due to BMC vulnerabilities.
- These vulnerabilities have existed for over a decade, indicating a long-standing security oversight.
- Attackers can gain persistent access, posing a significant threat to datacenter security.

## Why it matters

The discovery of these vulnerabilities highlights the urgent need for enhanced security measures in server management systems, as they can lead to severe data breaches and operational disruptions. Organizations must prioritize addressing these flaws to protect their infrastructure.

- **Product managers:** For product managers, this situation underscores the importance of incorporating robust security features in server products and ensuring that vulnerabilities are addressed proactively to maintain customer trust and avoid potential liabilities.
- **Developers:** Developers and engineers should focus on implementing secure coding practices and regularly updating firmware to mitigate risks associated with known vulnerabilities, especially in critical components like BMCs.
- **Students and job seekers:** For students and job-seekers, understanding these vulnerabilities presents an opportunity to explore careers in cybersecurity, emphasizing the importance of security in hardware and software development.

### 数千台服务器可通过利用有缺陷的主板控制器被后门化

近期研究揭示了主要制造商生产的数千台服务器的基础板管理控制器（BMC）存在重大漏洞。这些缺陷中有一些已存在超过十年，使攻击者能够利用BMC远程执行恶意代码，可能导致对关键数据中心资源的持续访问。这些漏洞的影响严重，可能导致对服务器操作的未经授权控制和敏感数据泄露。

**要点：**

- 由于BMC漏洞，数千台服务器面临风险。
- 这些漏洞存在超过十年，表明长期的安全疏忽。
- 攻击者可以获得持续访问，给数据中心安全带来重大威胁。

**为什么重要：** 这些漏洞的发现突显了在服务器管理系统中加强安全措施的迫切需要，因为它们可能导致严重的数据泄露和操作中断。组织必须优先解决这些缺陷以保护其基础设施。
