Summary

CVE-2024-6028 is a critical-severity SQL Injection (CWE-89) vulnerability in Ays-Pro Quiz Maker. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4% 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.

Deeper analysis AI-assisted summary

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

The Quiz Maker plugin for WordPress is vulnerable to time-based SQL Injection via the 'ays_questions' parameter in all versions up to and including 6.5.8.3. The flaw is caused by insufficient escaping of the user-supplied value combined with the absence of prepared statements on an existing SQL query, classified as CWE-89.

Unauthenticated attackers can exploit the issue remotely without user interaction to append additional SQL statements, enabling extraction of sensitive database contents and carrying full impact on confidentiality, integrity, and availability per the CVSS 9.8 rating.

References in the WordPress plugin repository document the corrective changesets applied to class-quiz-maker-public.php, with remediation appearing in versions 6.5.8.2 and 6.5.8.4; site administrators are advised to update through the official plugin directory.

The associated EPSS score stands at a current value of 0.8030 with a recorded peak of 0.8191.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

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

SI-10 Information Input Validation good match

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

SA-8 Security and Privacy Engineering Principles partial match

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

SI-4 System Monitoring partial match

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

PR.PS-06 mostly match
blocks

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
blocks

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.

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

A.8.28 Secure coding partial match
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.
