CVE-2021-25125
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 · uneditedThe Baseboard Management Controller(BMC) in HPE Cloudline CL5800 Gen9 Server; HPE Cloudline CL5200 Gen9 Server; HPE Cloudline CL4100 Gen10 Server; HPE Cloudline CL3100 Gen10 Server; HPE Cloudline CL5800 Gen10 Server BMC firmware has a local spx_restservice delsolrecordedvideo_func function path traversal 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 · high confidenceA path traversal vulnerability exists in the BMC firmware's spx_restservice delsolrecordedvideo_func function on HPE Cloudline CL5800 Gen9, CL5200 Gen9, CL4100 Gen10, CL3100 Gen10, and CL5800 Gen10 servers. This local vulnerability allows attackers with access to the BMC to traverse directories and access arbitrary files on the underlying system.

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 server modelCheck the HPE Cloudline server model via iLO/BMC web interface, IPMI command, or physical label. Confirm it is one of: CL5800 Gen9, CL5200 Gen9, CL4100 Gen10, CL3100 Gen10, or CL5800 Gen10.Affected if The model matches any of the five affected Cloudline models.
-
Retrieve the BMC firmware versionAccess the BMC web interface and navigate to the firmware information page, or use IPMI command: ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> raw command to get firmware version. Also check via HPE iLO or BIOS post screen.Affected if The BMC firmware version exactly matches: 1.08.0.0, 1.10.0.0, 1.07.0.0, or 1.09.0.0 for the respective model.
-
Verify spx_restservice is exposedConfirm the BMC REST API service (spx_restservice) is accessible on the BMC. This is typically available on port 443 or 80 via the BMC web interface. Test with: curl -k https://<BMC_IP>/api or check service status via BMC diagnostics.Affected if The BMC REST API endpoint is reachable and the delsolrecordedvideo_func function is present in the firmware.
-
Confirm local attack surfaceReview BMC access controls and network exposure. Check if the BMC management interface is accessible from untrusted networks or if physical access to the server is possible for local attackers.Affected if The BMC is accessible to untrusted users or the server has untrusted local access, allowing interaction with the vulnerable delsolrecordedvideo_func.
A user is affected if they are running one of the five HPE Cloudline server models with a BMC firmware version matching exactly 1.07.0.0, 1.08.0.0, 1.09.0.0, or 1.10.0.0, and the BMC interface is accessible to attackers who could exploit the path traversal in the delsolrecordedvideo_func.

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 HPE firmware update for affected Cloudline servers when available, and restrict physical and local network access to the BMC management interface to minimize attack surface.
