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 · unedited
Use of weak credentials exists in SkyBridge MB-A100/110 firmware Ver. 4.2.0 and earlier, which may allow a remote unauthenticated attacker to decrypt password for the WebUI of the product.

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 confidence

The SkyBridge MB-A100/110 firmware versions 4.2.0 and earlier contain weak credentials for the WebUI interface, allowing a remote unauthenticated attacker to decrypt stored passwords. This appears to stem from weak password encryption or hashing mechanisms in the firmware.

MitigationUpdate the device firmware to a version newer than 4.2.0 when available from the vendor. Until then, restrict network access to the WebUI interface through firewall rules or network segmentation to limit exposure to remote attackers.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed firmware version
    Access the device's web interface or console and navigate to the firmware/version information page, or use SNMP/CLI commands to retrieve the firmware build number
    Affected if The displayed firmware version is 4.2.0 or earlier
  2. Verify the WebUI network exposure
    Check network configuration or firewall rules to determine if the device's web management interface (typically ports 80/443 or vendor-specified ports) is accessible from untrusted networks or the public internet
    Affected if The WebUI is exposed to networks outside the trusted administrative segment
  3. Confirm weak credential vulnerability
    Attempt to authenticate to the WebUI using known default credentials for the device, or examine password storage mechanisms if firmware extraction is possible
    Affected if Default credentials successfully authenticate, or passwords are found to be stored using weak encryption/hashing (e.g., cleartext, reversible encoding, or weak hashing without salt)

The environment is affected if the SkyBridge MB-A100/110 device runs firmware version 4.2.0 or earlier and has its WebUI accessible from an untrusted network, allowing remote attackers to exploit weak credential storage.

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 data
Upgrade available Upgrade to a release after 4.2.0
Interim mitigation

Update the device firmware to a version newer than 4.2.0 when available from the vendor. Until then, restrict network access to the WebUI interface through firewall rules or network segmentation to limit exposure to remote attackers.
