Security readout for executives and security teams
Plain-English summary
CVE-2026-1123 is a remotely reachable SQL injection issue in Yonyou KSOA 9.0. An unauthenticated attacker may manipulate a GET parameter to affect database confidentiality, integrity, and availability. Public exploit information is reported, but the provided sources do not show confirmed active exploitation or a vendor fix.
Executive priority
Treat this as a high-priority exposure review for any Yonyou KSOA 9.0 environment, especially if externally reachable. Public exploit availability and no cited vendor response increase urgency, even without confirmed active exploitation.
Technical view
The vulnerability affects /worksheet/work_mod.jsp in the HTTP GET Parameter Handler. Manipulation of the ID argument leads to SQL injection. CVSS v2 is 7.5 with network access, low complexity, and no authentication required. VulDB lists proof-of-concept exploit availability and no vendor response at disclosure time.
Likely exposure
Organizations running Yonyou KSOA 9.0 with the affected JSP reachable over a network are the likely exposed population. Internet-facing deployments carry higher risk. The supplied affected CPE is broad, but the described impacted version is KSOA 9.0.
Exploitation context
Sources state the attack can be launched remotely and that exploit material is publicly available and might be used. The CVE is not marked KEV in the provided bundle, so active exploitation should not be assumed from these sources alone.
Researcher notes
Evidence is mainly from VulDB, CVE records, and a linked GitHub issue. The vulnerable function is unspecified, and no official vendor advisory or patch is cited in the supplied sources. Avoid assuming impact beyond Yonyou KSOA 9.0 unless additional vendor evidence appears.
Mitigation direction
- Identify any Yonyou KSOA 9.0 deployments and their network exposure.
- Restrict access to KSOA administrative or worksheet paths where business operations allow.
- Monitor vendor advisories for an official patch or workaround.
- Use compensating controls such as WAF rules if vendor guidance is unavailable.
- Review database account privileges used by KSOA and reduce excessive permissions.
Validation and detection
- Inventory KSOA versions and confirm whether 9.0 is present.
- Check whether /worksheet/work_mod.jsp is reachable from untrusted networks.
- Review web and database logs for suspicious requests to the affected path.
- Confirm whether vendor updates or guidance have been released since disclosure.
- Validate compensating controls block abnormal ID parameter input without disrupting business workflows.
