Security readout for executives and security teams
Plain-English summary
CVE-2026-1120 is a remotely reachable SQL injection in Yonyou KSOA 9.0. An attacker could manipulate a GET parameter in /worksheet/del_work.jsp to affect database confidentiality, integrity, and availability. Public exploit information is reported, but active exploitation is not confirmed by KEV or the provided sources.
Executive priority
Treat as high priority if Yonyou KSOA 9.0 is deployed, especially if externally reachable. Public exploit disclosure increases risk, but active exploitation is not confirmed. Prioritize asset discovery, exposure reduction, monitoring, and vendor guidance tracking.
Technical view
The issue affects the HTTP GET Parameter Handler for /worksheet/del_work.jsp in Yonyou KSOA 9.0. Manipulation of the ID argument leads to SQL injection. CVSS v2 is 7.5 with network access, low complexity, and no authentication. VulDB maps it to CWE-89 and CWE-74.
Likely exposure
Organizations running Yonyou KSOA 9.0 with the affected endpoint reachable over a network are potentially exposed. Internet-facing deployments carry higher urgency. The sources do not confirm other versions or products as affected.
Exploitation context
The vulnerability can be initiated remotely and public exploit material is referenced. The CVE is not listed as KEV in the provided data, so active exploitation should not be assumed. Vendor contact reportedly received no response, and no official patch is identified in the provided sources.
Researcher notes
Evidence is primarily from CVE/VulDB and a referenced GitHub issue. The affected function is described as unknown, and no vendor advisory or fix is cited. Avoid assuming impact beyond KSOA 9.0 or confirming exploitation without additional evidence.
Mitigation direction
- Identify whether Yonyou KSOA 9.0 is deployed in your environment.
- Restrict network access to KSOA, especially from the internet.
- Monitor vendor and CVE sources for official remediation guidance.
- Apply vendor-provided updates or configuration guidance when available.
- Increase logging and monitoring around /worksheet/del_work.jsp access.
Validation and detection
- Confirm deployed Yonyou KSOA version and exposure path.
- Check whether /worksheet/del_work.jsp is reachable from untrusted networks.
- Review web and database logs for unusual ID parameter activity.
- Verify compensating controls restrict access to the affected endpoint.
- Track CVE and VulDB updates for changes in affected versions or fixes.
