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
The web interface on Dell PowerConnect 6248P switches allows remote attackers to cause a denial of service (device crash) via a malformed request.

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 web interface on Dell PowerConnect 6248P switches contains a vulnerability that allows remote attackers to cause a denial of service via malformed HTTP requests. The vulnerability results in device crash, likely due to improper input validation or error handling in the web service component.

MitigationRestrict network access to the switch management interface using ACLs or firewall rules to prevent untrusted external hosts from reaching the web UI. If possible, disable the web interface and use CLI-based management instead.

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 switch model
    Check the device model number via CLI (show system) or physical label. Confirm it is a Dell PowerConnect 6248P.
    Affected if The device model is Dell PowerConnect 6248P.
  2. Verify the web interface is enabled
    Check the switch configuration for web management interface status via CLI: show running-config | include http or show ip http.
    Affected if HTTP or HTTPS web management is enabled in the configuration.
  3. Confirm web interface is network-accessible
    Verify the web interface IP address is reachable from external networks. Check VLAN configurations and management VLAN settings. Attempt to reach http://<management-ip> from an untrusted network segment.
    Affected if The web management interface IP is accessible from untrusted networks.

You are affected if you own a Dell PowerConnect 6248P switch and its web interface is enabled and reachable from untrusted networks.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict network access to the switch management interface using ACLs or firewall rules to prevent untrusted external hosts from reaching the web UI. If possible, disable the web interface and use CLI-based management instead.
