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 Yonyou KSOA 9.0. The affected element is an unknown function of the file /worksheet/agent_worksdel.jsp of the component HTTP GET Parameter Handler. Performing a manipulation of the argument ID results in sql injection. Remote exploitation of the attack is possible. The exploit has been made public and could 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 confidence

A SQL injection vulnerability exists in Yonyou KSOA 9.0 within the /workshop/agent_worksdel.jsp file. The ID GET parameter is not properly sanitized, allowing remote attackers to inject arbitrary SQL commands. The exploit is publicly available and the CVSS 9.8 score indicates critical impact requiring immediate attention.

MitigationImplement parameterized queries or prepared statements for all database operations involving the ID parameter. Apply input validation and restrict database privileges to limit the impact of any successful SQL injection.

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 Yonyou KSOA installation and version
    Locate the Yonyou KSOA installation directory and check version information in product documentation, About pages, or installation files. Common paths may include /ksoa or similar application directories.
    Affected if The installed version is Yonyou KSOA 9.0
  2. Verify the vulnerable JSP file exists
    Check for the presence of /worksheet/agent_worksdel.jsp in the web application's document root or deployed application directory.
    Affected if The file agent_worksdel.jsp exists in the /worksheet/ directory of the deployed application
  3. Confirm the ID parameter is accessible
    Attempt to access the endpoint with a GET request to /worksheet/agent_worksdel.jsp and verify the application processes the ID parameter.
    Affected if The endpoint responds and accepts the ID parameter without requiring authentication or input sanitization
  4. Check if application is network exposed
    Determine if the Yonyou KSOA web interface is accessible from network locations, including external networks or the internet.
    Affected if The application is exposed to untrusted networks without proper network segmentation or authentication gates

You are affected if Yonyou KSOA version 9.0 is deployed with the /worksheet/agent_worksdel.jsp endpoint accessible and the application processes the ID parameter without sanitization.
