CVE-2025-6198
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThere is a vulnerability in the Supermicro BMC firmware validation logic at Supermicro MBD-X13SEM-F . An attacker can update the system firmware with a specially crafted image.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability exists in the Supermicro BMC (Baseboard Management Controller) firmware validation logic on the X13SEM-F motherboard. The firmware validation mechanism can be bypassed, allowing an attacker to install a specially crafted malicious firmware image onto the system through the BMC update function.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the motherboard modelRun command 'dmidecode -t baseboard' or check Supermicro system documentation to confirm the exact motherboard model is X13SEM-FAffected if The system is a Supermicro X13SEM-F motherboard - other Supermicro models are not affected by this specific vulnerability
-
Check the BMC firmware versionAccess BMC web interface or run 'ipmitool -I lanplus -H <BMC_IP> -U admin -P <password> raw' command to retrieve firmware version, or check Supermicro's firmware release notes for the patched version numberAffected if The installed BMC firmware version is older than Supermicro's patched version for this CVE - you must compare against Supermicro's official advisory
-
Verify BMC management interface accessibilityCheck network configuration and firewall rules to determine if the BMC web interface (ports 80/443) or IPMI (port 623) is exposed to untrusted networksAffected if The BMC management interface is accessible from untrusted network segments - the vulnerability requires network access to the BMC update function
-
Confirm BMC firmware update feature statusAccess BMC web interface under 'Maintenance' or 'Firmware Update' section, or use IPMI command 'ipmitool -I lanplus -H <BMC_IP> -U admin -P <password> raw 0x3c 0x12' to check if firmware upload is permittedAffected if The BMC firmware update/upload functionality is enabled and accessible - the attack vector requires this feature to be reachable
-
Audit BMC user accounts and authenticationReview BMC user list using 'ipmitool -I lanplus -H <BMC_IP> -U admin -P <password> user list' and check for weak or default credentialsAffected if The BMC has weak, default, or compromised credentials - authentication is required to access the firmware update function
You are affected if you are running a Supermicro X13SEM-F motherboard with BMC firmware versions older than the patched release, and the BMC management interface with firmware update capability is accessible to an attacker.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Supermicro BMC firmware patch when available. Until then, restrict access to the BMC management interface to authorized personnel only, use strong authentication, and implement network segmentation for out-of-band management ports.
