Malicious BMC response reaches the client over the network (AV:N) but only when an operator runs the idrac-info subcommand (UI:R); overflow enables code execution, so C/I/A:H.

vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

DescriptionCVE.org

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _get_dell_system_info_idrac_info in ipmi-oem/ipmi-oem-dell.c (idrac-info subcommand to dell get-system-info).

AnalysisAI

Stack-based buffer overflow in FreeIPMI's ipmi-oem utility (versions before 1.6.19) lets a malicious or compromised Dell iDRAC BMC corrupt the memory of the client host running the 'dell get-system-info idrac-info' subcommand, potentially achieving code execution in the context of the operator (often root). The flaw sits in _get_dell_system_info_idrac_info in ipmi-oem/ipmi-oem-dell.c, which copies attacker-influenced OEM response data into a fixed-size stack buffer without bounds checking. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the victim to run the FreeIPMI ipmi-oem 'dell get-system-info idrac-info' subcommand against a BMC the attacker controls, has compromised, or can impersonate on the network - i.e., attacker control over the queried iDRAC's OEM response is the concrete prerequisite. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The input CVSS of 9.8 (AV:N/AC:L/PR:N/UI:N) overstates realistic risk because it models the BMC as the attacker and the ipmi-oem client as the target: exploitation is not a spontaneous remote hit against a listening service but is triggered only when an operator deliberately runs the Dell idrac-info subcommand against a BMC the attacker already controls or has compromised, which realistically implies UI:R and reduces the score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to FreeIPMI 1.6.19 or later (Vendor-released patch: 1.6.19), available from https://ftp.gnu.org/gnu/freeipmi/freeipmi-1.6.19.tar.gz or via distribution package updates once they rebuild against 1.6.19. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all systems running FreeIPMI versions before 1.6.19, focusing on those with root or privileged operator access, and assess your iDRAC network security posture. …
