Deeper analysis
CVE-2025-15435 is a SQL injection vulnerability in Yonyou KSOA 9.0, affecting the /worksheet/work_update.jsp endpoint through manipulation of the Report argument. Classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and lack of prerequisites.
The vulnerability can be exploited remotely by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling data exfiltration, modification, or disruption within the application's database.
Advisories from VulDB (ctiid.339362, id.339362, submit.721918) and a GitHub issue (xiaozipang/CVE/issues/1) detail the flaw, with a public exploit available. The vendor was notified early but has not responded or issued patches, leaving affected systems without official mitigations.

Mandatory validation and sanitization of the Report argument in work_update.jsp would block the crafted SQL payloads that exploit this CWE-89 flaw.
Restricting the application's database account to least-privilege rights would limit the confidentiality, integrity, and availability impact even if the SQL injection succeeds.
Prompt application of vendor patches or custom fixes for the published exploit in /worksheet/work_update.jsp directly eliminates the unpatched vulnerability.
