Summary

CVE-2023-37931 is a high-severity SQL Injection (CWE-89) vulnerability in Fortinet Fortivoice. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-37931 is a SQL injection vulnerability (CWE-89) in FortiVoice Enterprise versions 7.0.0 through 7.0.1 and before 6.4.8. The flaw stems from improper neutralization of special elements used in an SQL command, allowing an authenticated attacker to execute a blind SQL injection attack by sending crafted HTTP or HTTPS requests. It has 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), indicating high severity due to its potential for significant impact.

An attacker requires low-privilege authenticated access (PR:L) to exploit the vulnerability over the network (AV:N) with low attack complexity and no user interaction. Exploitation enables a blind SQL injection, potentially allowing the attacker to extract sensitive data, modify database contents, or disrupt system availability, achieving high levels of confidentiality, integrity, and availability impact.

The FortiGuard PSIRT advisory FG-IR-23-220 provides details on mitigation and patches; security practitioners should consult https://fortiguard.com/psirt/FG-IR-23-220 for upgrade guidance and remediation steps.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

Input validation directly stops untrusted data from reaching SQL query construction without neutralization.

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
