CVE-2025-54857
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 · uneditedImproper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in SkyBridge BASIC MB-A130 Ver.1.5.8 and earlier. If exploited, a remote unauthenticated attacker may execute arbitrary OS commands with root privileges.
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 confidenceOS Command Injection vulnerability in SkyBridge BASIC MB-A130 firmware version 1.5.8 and earlier allows remote unauthenticated attackers to execute arbitrary OS commands with root privileges. The vulnerability stems from improper neutralization of special elements in user input that gets passed to underlying OS command execution, enabling complete system compromise.

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 device modelCheck the device label, web interface, or SNMP/management console for the model name 'SkyBridge BASIC MB-A130'Affected if The device is not a SkyBridge BASIC MB-A130 (different models are not affected)
-
Determine the firmware versionAccess the device's web management interface or check the firmware file loaded on the device. Look for a version indicator in the system info or about page.Affected if Firmware version is 1.5.8 or earlier, or the version cannot be determined (assume affected if unverifiable)
-
Verify remote access exposureCheck network configuration to determine if the device management interface (typically HTTP/HTTPS on port 80/443 or other management ports) is accessible from untrusted networks or the public internet.Affected if The management interface is exposed to untrusted networks (this is required for the remote unauthenticated attack vector)
-
Check for suspicious processes or connectionsIf you have shell access (via console or limited diagnostic mode), run commands like 'ps aux' or 'netstat -an' to look for unexpected processes listening on network ports or suspicious outbound connections.Affected if Unexpected processes or unusual network connections are found that may indicate compromise
The environment is affected if the device is a SkyBridge BASIC MB-A130 running firmware version 1.5.8 or earlier and its management interface is accessible from untrusted networks.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply vendor firmware update when available; as interim measures, restrict network access to the device and implement network segmentation to limit exposure to untrusted networks.
Ver.1.5.9 or later (verify with vendor)
- 1. Identify the current installed version of SkyBridge BASIC MB-A130 on the affected device
- 2. Check the vendor website (www.seiko-sol.co.jp) or JVN (jvn.jp) for the latest security patches or firmware updates
- 3. If a version newer than Ver.1.5.8 is available, obtain the update from the official vendor source
- 4. Follow the vendor's official upgrade instructions to apply the patch
- 5. After upgrading, verify the version to confirm the patch was applied successfully
- 6. Restrict network access to the device management interface to minimize exposure
