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
Changing the password on the module webpage does not require the user to type in the current password first. Thus, the password could be changed by a user or external process without knowledge of the current password on the ICX35-HWC-A and ICX35-HWC-E (Versions 1.9.62 and prior).

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 confidence

The ICX35-HWC-A and ICX35-HWC-E web management interfaces allow password changes without verifying the user's current password, enabling unauthorized password modification by anyone with web access to the device.

MitigationUpdate firmware to a version newer than 1.9.62 when available. Until then, restrict network access to the device's web interface and monitor for unauthorized configuration changes.

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 ICX35-HWC devices on the network
    Scan the network for devices with Prosoft Technology ICX35-HWC-A or ICX35-HWC-E hostnames, or check network inventory/asset lists for these model numbers
    Affected if Prosoft Technology ICX35-HWC-A or ICX35-HWC-E devices are present in the environment
  2. Check the firmware version
    Access the device's web management interface or check the device firmware version via its admin console, SNMP, or device documentation. Compare the installed version against the affected range <= 1.9.62
    Affected if The firmware version is 1.9.62 or lower
  3. Determine if the web management interface is accessible
    Attempt to reach the device's web interface via HTTP/HTTPS from the network segments that have access, or review firewall/network access control lists for rules permitting access to the device's web ports
    Affected if The web management interface is reachable from any network segment accessible to users or attackers

If the environment contains ICX35-HWC-A or ICX35-HWC-E devices running firmware version 1.9.62 or lower with an accessible web management interface, the environment is affected by this vulnerability.

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 1.9.62
Interim mitigation

Update firmware to a version newer than 1.9.62 when available. Until then, restrict network access to the device's web interface and monitor for unauthorized configuration changes.
