Summary

CVE-2025-15434 is a medium-severity Injection (CWE-74) vulnerability in Yonyou Ksoa. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).

Deeper analysis

CVE-2025-15434 is a SQL injection vulnerability affecting Yonyou KSOA 9.0, specifically an unknown function in the file /kp/PrintZPYG.jsp. The issue arises from improper handling of the zpjhid parameter, allowing injection of malicious SQL payloads. It has 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 is associated with CWE-74 (injection) and CWE-89 (SQL injection). The vulnerability was published on 2026-01-02.

The vulnerability can be exploited remotely by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or denial of service within the application's database.

Advisories from VulDB and a GitHub issue detail the vulnerability but note no vendor response or patch availability despite early notification. The exploit is publicly available, increasing the risk of immediate exploitation attempts.

Notable context includes the public disclosure of the exploit code, with no reported real-world exploitation or relevance to AI/ML at this time.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and sanitization of the zpjhid parameter in PrintZPYG.jsp to block malicious SQL payloads before they reach the database.

prevent

Enforces least-privilege database accounts so that even a successful injection via the unauthenticated zpjhid parameter yields only limited confidentiality/integrity/availability impact.

detect

Enables monitoring of application and database query patterns to identify anomalous inputs or SQL statements originating from the /kp/PrintZPYG.jsp endpoint.
