CVE-2022-40259

CVE-2022-40259 is a software vulnerability that was part of a series of bugs affecting AMI MegaRAC Baseboard Management Controllers (BMCs), collectively referred to as BMC&C. This flaw in software design or implementation was disclosed along with other vulnerabilities in December 2022, including CVE-2022-40242 and CVE-2022-2827. The discovery of these vulnerabilities highlighted the potential for exploitation through dangerous commands in the BMC's API or via default credentials, which could enable remote code execution. Despite its severity, CVE-2022-40259 was considered less critical than two other vulnerabilities disclosed at the same time. According to an advisory by Eclypsium, CVE-2022-40259 and CVE-2022-40242 allowed for relatively simple remote code execution. However, these were not the only vulnerabilities discovered during this period; additional bugs were revealed in January 2023 (CVE-2022-26872 and CVE-2022-40258) further contributing to the issues surrounding the AMI MegaRAC BMCs. The continuous discovery of these vulnerabilities demonstrates the persistent security challenges facing the AMI MegaRAC BMCs. Notably, the disclosure of CVE-2022-40259 and other related vulnerabilities has been instrumental in shedding light on the potential risks associated with software flaws in such systems. As a result, stakeholders have been urged to take necessary measures to address these vulnerabilities and enhance the overall security of their systems.
