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 vulnerability was found in TRENDnet TEW-652BRP 3.04b01 and classified as problematic. This issue affects some unknown processing of the file get_set.ccp of the component Web Management Interface. The manipulation of the argument nextPage leads to cross site scripting. The attack may be initiated remotely. The associated identifier of this vulnerability is VDB-220019.

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

Cross-site scripting (XSS) vulnerability in TRENDnet TEW-652BRP router web management interface. The get_set.ccp component fails to properly sanitize user input in the 'nextPage' parameter, allowing remote attackers to inject malicious JavaScript code that executes in the context of an authenticated user's browser.

MitigationApply vendor firmware patch if available; if no patch exists, implement network segmentation to isolate the device or consider replacing the end-of-life device. Disable remote web management if not required.

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 device model
    Check the router label or access the web management interface to confirm the model is TRENDnet TEW-652BRP
    Affected if Device is not a TEW-652BRP model
  2. Check the installed firmware version
    Access the router web management interface, typically at http://192.168.10.1, and navigate to the Status or System section to view the firmware version. Alternatively, check the label on the device itself.
    Affected if Firmware version is exactly 3.04b01
  3. Verify web management interface accessibility
    Attempt to access the router's web interface on ports 80 or 443 from the local network. Check if the interface is exposed to the internet via port forwarding or DMZ settings.
    Affected if Web management is accessible (even locally, the XSS could execute if an authenticated user visits a crafted link)
  4. Confirm the get_set.ccp endpoint exists
    Attempt to access the vulnerable endpoint by navigating to a URL such as http://192.168.10.1/get_set.ccp or inspecting the router's web interface source code for references to this component.
    Affected if The get_set.ccp component is present and accessible

You are affected if you have a TRENDnet TEW-652BRP router running firmware version 3.04b01 and its web management interface is accessible.
