CVE-2025-5140
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 · uneditedA vulnerability classified as critical has been found in Seeyon Zhiyuan OA Web Application System up to 8.1 SP2. This affects the function this.oursNetService.getData of the file com\ours\www\ehr\openPlatform1\open4ClientType\controller\ThirdMenuController.class. The manipulation of the argument url leads to server-side request forgery. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceServer-side request forgery (SSRF) in Seeyon Zhiyuan OA Web Application System's ThirdMenuController component allows remote attackers to make the server perform arbitrary HTTP requests by manipulating the 'url' parameter passed to the oursNetService.getData function. The vulnerability affects versions up to 8.1 SP2 and is exploitable remotely without authentication.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Seeyon Zhiyuan OA installationIdentify if Seeyon Zhiyuan OA Web Application System is deployed in your environment by checking for its web directories, services, or process names typically found under the application server's webroot.Affected if The application is present in the environment
-
Determine the installed versionLocate version information in the system, typically found in version files, about pages, or configuration files within the Seeyon OA installation directory. Compare the version number to the affected range: versions up to and including 8.1 SP2.Affected if The installed version is 8.1 SP2 or earlier
-
Verify ThirdMenuController accessibilityCheck if the ThirdMenuController endpoint is accessible on the web server. This is typically found under the application's web interface paths such as /seeyon/ThirdMenuController or similar URL patterns.Affected if The ThirdMenuController endpoint is exposed and reachable over the network
-
Confirm url parameter exposureTest or inspect whether the 'url' parameter can be passed to the oursNetService.getData function through the ThirdMenuController. This may be observed in application logs or by reviewing accessible web service endpoints.Affected if The 'url' parameter is accepted by the ThirdMenuController without proper validation
A user is affected if Seeyon Zhiyuan OA version 8.1 SP2 or earlier is installed with the ThirdMenuController endpoint exposed and accepting the 'url' parameter.

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 dataImplement strict allowlist validation for the url parameter to restrict requests to trusted domains/IPs only; additionally, apply network segmentation to limit server outbound connectivity and monitor for suspicious internal requests.
