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 flaw has been found in xiweicheng TMS up to 2.28.0. This affects the function Summary of the file src/main/java/com/lhjz/portal/util/HtmlUtil.java. This manipulation of the argument url causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been published and may be used.

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 server-side request forgery (SSRF) vulnerability exists in xiweicheng TMS up to version 2.28.0 in the Summary function of HtmlUtil.java. The function accepts a user-controlled URL parameter and makes server-side requests to it without proper validation, allowing attackers to abuse the server to scan internal resources or access cloud metadata services.

MitigationImplement strict URL allowlist validation to restrict accessible domains/IPs, disable the ability to fetch arbitrary URLs if not business-critical, and upgrade to a patched version when 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 the installed version of Xiweicheng TMS
    Locate the application version information - check the about page, config files, or the war/jar manifest. Compare the version number against the affected range (<= 2.28.0)
    Affected if The installed version is 2.28.0 or lower
  2. Locate the HtmlUtil.java component
    Search the application codebase or deployed files for HtmlUtil.java and verify the Summary function exists
    Affected if The file exists with the Summary function present in the application
  3. Verify the Summary endpoint is accessible
    Identify if there is an HTTP endpoint that invokes the Summary function in HtmlUtil.java - typically this would be a web request that triggers URL fetching functionality
    Affected if The Summary endpoint is exposed and reachable without authentication or with low-privileged user access
  4. Check for user-controlled URL parameters
    Review the application requests that invoke the Summary function - look for parameters that accept URLs and are passed to server-side request operations
    Affected if The application accepts arbitrary URLs from user input and uses them in server-side HTTP requests
  5. Inspect access logs for SSRF indicators
    Review application and web server logs for requests to internal IP ranges (127.0.0.1, 10.x.x.x, 192.168.x.x), cloud metadata endpoints (169.254.169.254), or unusual outbound patterns from the Summary functionality
    Affected if Logs show requests to internal resources or metadata services originating from the server

You are affected if Xiweicheng TMS version is 2.28.0 or lower AND the Summary function in HtmlUtil.java is accessible, allowing user-supplied URLs to trigger server-side requests.
