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 has been found in Yonyou KSOA 9.0. Affected by this issue is some unknown functionality of the file /worksheet/work_edit.jsp. Such manipulation of the argument Report leads to sql injection. The attack can be launched 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 confidence

SQL injection vulnerability in Yonyou KSOA 9.0's /worksheet/work_edit.jsp file allows remote attackers to inject malicious SQL queries through the Report parameter, potentially leading to unauthorized database access or manipulation.

MitigationImplement parameterized queries or prepared statements for the Report parameter in work_edit.jsp to prevent SQL injection. Since the vendor did not respond, consider network segmentation to limit exposure and monitor for exploitation attempts.

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. Confirm Yonyou KSOA installation exists
    Locate Yonyou KSOA in your environment by identifying the web application's deployment directory or by checking for the characteristic application files and folder structure typically associated with KSOA installations.
    Affected if Yonyou KSOA is not present in the environment, then this CVE does not apply.
  2. Verify the installed KSOA version
    Determine the exact version of Yonyou KSOA by checking the application's version information, typically found in the software's about page, installation metadata, or version file within the deployment directory.
    Affected if The installed version is not 9.0, then this CVE does not apply.
  3. Check for presence of vulnerable work_edit.jsp
    Locate the /worksheet/work_edit.jsp file within the web application's deployment directory. This file should exist in the worksheet subdirectory of the web root.
    Affected if The work_edit.jsp file does not exist in the expected location, then this specific CVE may not be present.
  4. Verify network accessibility of the vulnerable endpoint
    Confirm whether the web application and specifically the /worksheet/work_edit.jsp endpoint is accessible from the network by attempting to access the URL or reviewing network exposure configurations.
    Affected if The application is not network-accessible (only localhost or strictly internal), the exploit vector is significantly reduced.
  5. Inspect the Report parameter handling in work_edit.jsp
    Examine the source code of work_edit.jsp to verify that the Report parameter is directly incorporated into SQL queries without proper parameterized query implementation or input sanitization.
    Affected if The Report parameter uses prepared statements or proper input sanitization, the SQL injection vulnerability is mitigated.

The environment is affected if Yonyou KSOA version 9.0 is installed, the /worksheet/work_edit.jsp file exists, and the Report parameter is handled without parameterized queries in the application's code.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement parameterized queries or prepared statements for the Report parameter in work_edit.jsp to prevent SQL injection. Since the vendor did not respond, consider network segmentation to limit exposure and monitor for exploitation attempts.
