CVE-2025-8076
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 web function at Supermicro MBD-X13SEDW-F. After logging into the BMC Web server, an attacker can use a specially crafted payload to trigger the Stack buffer overflow vulnerability.
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 confidenceStack buffer overflow vulnerability in the Supermicro BMC web interface on the X13SEDW-F motherboard. The flaw exists in a web function that processes user input after authentication, allowing a remote attacker with valid BMC credentials to send a specially crafted payload that overflows a stack-based buffer, potentially leading to code execution.

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.
-
Confirm Supermicro BMC modelAccess the BMC web interface or use IPMI commands (e.g., 'ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> raw ...' or check the web interface login page footer) to identify the motherboard model. Look for X13SEDW-F or other X13 series Supermicro boards.Affected if The system is a Supermicro BMC on an X13SEDW-F motherboard or related X13 series board.
-
Check BMC firmware versionLog into the BMC web interface and navigate to the 'Maintenance' or 'Firmware Update' section to view the current firmware version. Alternatively, use IPMI: 'ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> raw 0x06 0x01' or check the 'BMC Information' page.Affected if The installed BMC firmware version is unknown or unpatched (no patch version is specified in available advisories).
-
Verify web interface accessibilityAttempt to reach the BMC web interface over HTTP/HTTPS (ports 80/443 or custom ports) from a remote location. Use a browser or curl: 'curl -k https://<BMC_IP>/'. Check if the login page is accessible.Affected if The BMC web interface is reachable from untrusted networks or the internet.
-
Check BMC credential configurationReview the list of BMC users via the web interface (under 'User Management' or 'Administrative' settings) or via IPMI: 'ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> user list'. Identify if default, weak, or shared credentials are in use.Affected if Valid BMC credentials exist (even if strong), as the vulnerability requires authenticated access to the web interface.
The environment is affected if it runs a Supermicro X13SEDW-F (or related X13 series) BMC with an unpatched firmware version, the web interface is accessible, and valid BMC credentials are configured.

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 BMC web interface access to trusted networks only, use strong unique credentials, and enable network segmentation to reduce exposure.
