Summary

CVE-2026-7489 is a high-severity SQL Injection (CWE-89) vulnerability in Sun.Net Ehrd Ctms. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-7489 is a SQL injection vulnerability (CWE-89) affecting CTMS, a product developed by Sunnet. The flaw enables authenticated remote attackers to inject arbitrary SQL commands, allowing them to read, modify, and delete database contents. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and was published on 2026-05-02T10:16:18.803.

Authenticated remote attackers with low privileges can exploit this vulnerability over the network with low attack complexity and without requiring user interaction. Successful exploitation results in high impacts on confidentiality, integrity, and availability, potentially leading to complete database compromise through unauthorized data access, alteration, or destruction.

Advisories from TWCERT/CC, available at https://www.twcert.org.tw/en/cp-139-10895-25ca1-2.html and https://www.twcert.org.tw/tw/cp-132-10894-1ac1f-1.html, provide further details on the issue.

MITRE ATT&CK Enterprise TechniquesAI

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.
attack.mitre.org →
T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
attack.mitre.org →
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
attack.mitre.org →
T1485 Data Destruction Impact
Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources.

Why these techniques?

SQL injection in remotely accessible application directly enables T1190 exploitation and facilitates T1213.006 database data collection, T1565.001 stored data manipulation, and T1485 data destruction via read/modify/delete operations.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

SI-10 directly prevents SQL injection like CVE-2026-7489 by requiring validation and sanitization of user inputs before incorporation into database queries.

SI-2 Flaw Remediation good match
prevent

SI-2 requires organizations to identify, report, and remediate software flaws such as the SQL injection vulnerability in CTMS.

AC-6 Least Privilege partial match
prevent

AC-6 least privilege restricts database account permissions, limiting the scope of damage from successful SQL injection exploitation.
