Technical Analysis

The ipmi-oem module in FreeIPMI versions prior to 1.6.19 contains a stack-based buffer overflow vulnerability in the _output_dell_system_info_cmc_ipv6_info function. This function is part of the cmc-ipv6-info subcommand used by the dell get-system-info command. The vulnerability is identified as CWE-121 and has a CVSS 3.1 base score of 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and full impact on confidentiality, integrity, and availability.

Potential Impact

Successful exploitation of this vulnerability could allow an unauthenticated remote attacker to execute arbitrary code or cause a denial of service, resulting in full compromise of the affected system's confidentiality, integrity, and availability.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates and consider restricting access to the vulnerable functionality until a fix is available.
