Security News > 2023 > February > Additional Supply Chain Vulnerabilities Uncovered in AMI MegaRAC BMC Software

Two more supply chain security flaws have been disclosed in AMI MegaRAC Baseboard Management Controller software, nearly two months after three security vulnerabilities were brought to light in the same product.

Firmware security firm Eclypsium said the two shortcomings were held back until now to provide AMI additional time to engineer appropriate mitigations.

The issues, collectively tracked as BMC&C, could act as springboard for cyber attacks, enabling threat actors to obtain remote code execution and unauthorized device access with superuser permissions.

Specifically, MegaRAC has been found to use the MD5 hashing algorithm with a global salt for older devices, or SHA-512 with per user salts on newer appliances, potentially allowing a threat actor to crack the passwords.

CVE-2022-26872 and CVE-2022-40258 add to three other vulnerabilities disclosed in December, including CVE-2022-40259, CVE-2022-40242, and CVE-2022-2827.

"The impact of exploiting these vulnerabilities include remote control of compromised servers, remote deployment of malware, ransomware and firmware implants, and server physical damage," Eclypsium noted.
