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 cross-site scripting (XSS) vulnerability in SAP J2EE Engine 7.01 allows remote attackers to inject arbitrary web script via the wsdlPath parameter to /ctcprotocol/Protocol. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

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

A reflected cross-site scripting (XSS) vulnerability exists in SAP J2EE Engine 7.01. The wsdlPath parameter in the /ctcprotocol/Protocol endpoint does not properly sanitize user input, allowing remote attackers to inject arbitrary JavaScript or HTML via the URL parameter.

MitigationFor legacy unsupported products, consider network isolation or removal if possible. Otherwise, implement input validation and output encoding on the affected endpoint, or apply vendor-supplied patches if available.

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 SAP J2EE Engine version
    Use SAP administration tools or check system information files to determine the installed version of SAP J2EE Engine
    Affected if The installed version is exactly 7.01
  2. Verify ctcprotocol Protocol endpoint existence
    Attempt to access the URI /ctcprotocol/Protocol on the SAP J2EE Engine server to confirm the endpoint is exposed
    Affected if The endpoint responds with an HTTP 200 or error message indicating it exists
  3. Test wsdlPath parameter reflection
    Send a request to the endpoint with a test string such as <script>alert(1)</script> as the wsdlPath parameter and examine if the response reflects this input unescaped
    Affected if The input is reflected back in the response without HTML encoding

A system is affected only if it runs SAP J2EE Engine version 7.01 and exposes the vulnerable /ctcprotocol/Protocol endpoint where the wsdlPath parameter reflects unsanitized user input.
