On July 10, 2024, CISA and the FBI released a new Secure by Design Alert focusing on eliminating OS command injection vulnerabilities. This alert addresses recent cyber threat actor campaigns that exploited these vulnerabilities to compromise network edge devices. The vulnerabilities in question—CVE-2024-20399, CVE-2024-3400, and CVE-2024-21887—allowed attackers to remotely execute malicious code on affected devices.
OS command injection vulnerabilities have been known for some time and are typically preventable by ensuring that user input is properly separated from command contents. Despite this, such vulnerabilities remain common, primarily due to issues related to CWE-78. The persistence of these vulnerabilities highlights ongoing challenges in securing network edge devices and other systems.
CISA and the FBI are urging CEOs and technology leaders to take proactive measures to address these vulnerabilities. They recommend that organizations analyze past occurrences of these issues and develop strategies to prevent them in the future. The alert emphasizes the importance of adopting Secure by Design principles to enhance overall security.
For additional guidance on implementing these principles, organizations are directed to visit the Secure by Design webpage provided by CISA and the FBI. This initiative aims to support the tech industry in mitigating the risks associated with OS command injection vulnerabilities and improving device security.
