Deeper analysis
CVE-2025-15420 is a SQL injection vulnerability in Yonyou KSOA 9.0, affecting the /worksheet/agent_work_report.jsp file through manipulation of the ID argument. Published on 2026-01-02, 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) and maps to CWEs-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).
The vulnerability enables remote exploitation without authentication or user interaction, requiring low attack complexity. Attackers can manipulate the ID parameter to inject SQL payloads, potentially achieving limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or disruption.
Advisories from VulDB (ctiid.339342, id.339342, submit.721099, submit.721531) document the issue, and a GitHub repository details the exploit in the agent_work_report.jsp endpoint. The vendor was contacted early about the disclosure but provided no response, with no patches or official mitigations reported.
The exploit has been publicly disclosed and may be used in attacks.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and neutralization of untrusted input such as the ID parameter before it reaches SQL statements in agent_work_report.jsp.
Boundary protection mechanisms (e.g., WAF rules or input filtering at the perimeter) can inspect and block SQL injection payloads targeting the exposed JSP endpoint.
Least-privilege database accounts and query permissions limit the confidentiality/integrity/availability impact even if an unsanitized ID value is executed.
