CVE-2025-37139
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 · uneditedA vulnerability in an AOS firmware binary allows an authenticated malicious actor to permanently delete necessary boot information. Successful exploitation may render the system unbootable, resulting in a Denial of Service that can only be resolved by replacing the affected hardware.
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 in AOS firmware binary allows an authenticated attacker to permanently delete boot information, causing the device to become unbootable and requiring hardware replacement.

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 AOS firmware installationCheck your device's firmware information through the administrative console, boot logs, or system information commands (e.g., 'show version', 'firmware-info', or check /proc/version on the device if accessible). Confirm the firmware is identified as 'AOS' or an AOS-based product.Affected if The device runs AOS firmware and the installed version falls within any vulnerable range (compare your version to known affected versions if available).
-
Verify administrative access controlsReview user accounts and authentication settings in the device's administrative interface. Confirm that only authorized personnel have administrative credentials and that default credentials have been changed.Affected if The device allows authenticated administrative access, which is required for this vulnerability to be exploitable.
-
Check network exposure of administrative interfacesScan your network for open administrative ports (typically HTTP/HTTPS on ports 80, 443, or vendor-specific ports) on AOS devices. Verify that administrative interfaces are not accessible from untrusted networks.Affected if Administrative interfaces are exposed to untrusted networks, increasing the likelihood of unauthorized authenticated access.
-
Inspect boot configuration integrityIf accessible, check the boot configuration files or partition information on the device (e.g., 'show boot-config', 'cat /proc/bootinfo', or examine bootloader settings). Look for any signs of deletion, corruption, or unauthorized modification.Affected if Boot information has been deleted or modified, indicating the vulnerability may have been exploited.
A user is affected if their device runs AOS firmware and an authenticated attacker has gained administrative access to delete boot information, resulting in an unbootable device.

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 dataRestrict administrative access to trusted personnel only, implement network segmentation, and apply vendor firmware patches when available. Consider hardware replacement planning for affected devices.
