Breaking BMC: The Forgotten Key to the Kingdom - Security Vulnerabilities in Baseboard Management Controllers

Explore a detailed security analysis presentation from DEF CON 31 that reveals critical vulnerabilities in the Baseboard Management Controller (BMC) system, specifically focusing on NVIDIA hardware running AMI MegaRAC BMC. Learn how researchers discovered multiple remotely exploitable bugs, privilege escalation vulnerabilities, and scope change issues that can be chained together to create severe security breaches. Follow along a comprehensive attack sequence demonstration that progresses from initial access to an IPMI-enabled AMI BMC through to successfully implementing a persistent firmware implant on the server SPI flash. Understand the significant security implications of BMC vulnerabilities, given the controller's privileged access to hardware components and remote management capabilities, including firmware updates and power control.
