CISA and the FBI issued a critical “Secure by Design Alert” urging software developers to address OS command-injection vulnerabilities. Recent exploits, such as the CVE-2024-20399 bug in Cisco’s NX-OS software, demonstrate the potential for system takeovers and data leaks. The agencies advocate for a secure-by-design approach and OPSEC principles to mitigate these risks.
Based on the meeting notes, the key takeaways are:
1. CISA and the FBI have issued a critical alert urging software developers to address OS command-injection vulnerabilities that allow unauthorized users to execute harmful commands on operating systems.
2. Despite being preventable, OS command-injection vulnerabilities continue to be an issue, with recent high-profile campaigns exploiting these defects in network edge devices, such as the CVE-2024-20399 bug in Cisco’s NX-OS software.
3. These vulnerabilities occur due to the failure to properly validate and sanitize user inputs, leading to potential system takeovers, unauthorized code execution, and data leaks.
4. CISA and the FBI recommend a secure-by-design approach for technology manufacturers to eliminate these vulnerabilities at the source, and they call on business leaders to prioritize product security by integrating OPSEC principles into their development processes.
5. Recommended measures for addressing these vulnerabilities include using safer command-generation functions, reviewing threat models, utilizing modern component libraries, conducting thorough code reviews, and implementing aggressive adversarial product testing throughout the development life cycle.
