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
A security vulnerability in D-Link DGS-1510-series switches with firmware 1.20.011, 1.30.007, 1.31.B003 and older that may allow a remote attacker to inject malicious scripts in the device and execute commands via browser that is configuring the unit.

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

This is a stored Cross-Site Scripting (XSS) vulnerability in the web management interface of D-Link DGS-1510-series switches. A remote attacker can inject malicious JavaScript code into device configuration parameters, which then executes in the browser of administrators accessing the device's web interface to configure the switch, enabling command execution through the browser session.

MitigationUpgrade D-Link DGS-1510-series switches to a patched firmware version newer than 1.31.B003. If no patched firmware is available, disable the web management interface or restrict access to trusted IP addresses only.

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
    Access the device console or web interface and retrieve the hardware model information. This is typically visible on the device label, in the web interface header, or via CLI command 'show device info' or 'show system info'.
    Affected if The device model is any DGS-1510 series switch including DGS-1510-20, DGS-1510-28, DGS-1510-28p, DGS-1510-28x, DGS-1510-28xmp, DGS-1510-52, DGS-1510-52x, or DGS-1510-52xmp.
  2. Check the firmware version
    In the web interface, navigate to the System > Firmware or System > Device Information section to view the installed firmware version. Alternatively, use CLI command 'show firmware version' or 'show version'.
    Affected if The installed firmware version is 1.20.011, 1.30.007, or any version up to and including 1.31.B003.
  3. Verify the web management interface is enabled
    In the web interface, go to Management > Web Access or similar section to confirm HTTP or HTTPS web management is enabled. In CLI, check with commands like 'show web' or 'show ip http' or 'show ip https'.
    Affected if The web management interface (HTTP or HTTPS) is enabled and accessible.
  4. Inspect configuration parameters for injected scripts
    Review all configurable fields in the web interface where user-supplied values are stored, such as device name, description fields, VLAN names, port descriptions, or management IP settings. Check the running configuration via CLI with 'show running-config' for any unexpected HTML script tags or JavaScript code within parameter values.
    Affected if Any configuration parameter contains raw HTML script tags, javascript: URIs, or other XSS payload patterns that were not intentionally configured by the administrator.

The device is affected if it is a DGS-1510 series switch running firmware version 1.20.011, 1.30.007, or any version up to 1.31.B003, and the web management interface is enabled.

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 1.31.b003
Interim mitigation

Upgrade D-Link DGS-1510-series switches to a patched firmware version newer than 1.31.B003. If no patched firmware is available, disable the web management interface or restrict access to trusted IP addresses only.
