Summary

CVE-2025-15424 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 30.9th 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-2025-15424 is a SQL injection vulnerability in Yonyou KSOA 9.0, affecting an unknown function within the file /worksheet/agent_worksdel.jsp handled by the HTTP GET Parameter Handler component. The flaw arises from improper handling of the 'ID' argument in HTTP GET requests, allowing injection of malicious SQL payloads. It is classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), with 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).

The vulnerability enables remote exploitation over the network with low complexity and no required privileges or user interaction. Attackers can manipulate the 'ID' parameter to execute arbitrary SQL queries, potentially leading to limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or denial of service on the underlying database.

Advisories from VulDB and related GitHub repositories detail the vulnerability and provide proof-of-concept exploits but report no vendor response despite early disclosure contact. No patches, workarounds, or official mitigations are available, leaving affected systems reliant on network controls or input validation as interim defenses.

The exploit has been publicly disclosed, increasing the risk of widespread targeting against exposed Yonyou KSOA 9.0 instances.

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Direct remote SQL injection in a public-facing web app (Yonyou KSOA) via HTTP GET parameter enables initial access through exploitation of the exposed application.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and sanitization of the 'ID' HTTP GET parameter before it is used in SQL statements, blocking the injection vector in /worksheet/agent_worksdel.jsp.

detect

Enables continuous monitoring and anomaly detection on database queries or web requests containing unexpected SQL syntax in the ID parameter.

prevent

Restricts the database account used by the KSOA component to the minimum privileges needed, limiting the impact of any successful SQL injection.
