Operationally, ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Qualitor through version 8.20 contains a command-injection vulnerability (CWE-77) that permits unauthenticated remote code execution. The flaw resides in the gridValoresPopHidden parameter of html/ad/adpesquisasql/request/processVariavel.php, where attacker-supplied PHP code is processed without sanitization, allowing direct execution on the server.
An attacker with network access can submit a crafted request to the affected endpoint and obtain arbitrary code execution with the privileges of the web-server process. Successful exploitation yields full confidentiality, integrity, and availability impact, consistent with the CVSS 9.8 rating that requires no authentication or user interaction.
The associated EPSS score has reached 0.939, indicating a high likelihood of exploitation. Vendor advisories and updated releases are referenced at qualitor.com.br, including an official security advisory for CVE-2023-47253.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reduce command injection defects, but leaves a minority slice (e.g. incomplete implementation of those practices, outsourced development without full assurance, or post-SDLC changes) where the weakness can still arise and be exploitable.
Application security requirements explicitly call for controls against injection flaws including command injection.
A.8.27 mandates security-by-design principles (e.g. distrust external input, secure session control, data validation/sanitization, least privilege) and design reviews that can stop command injection from being introduced, but this is only a minority slice of CWE-77 because the weakness can still arise in code that bypasses those principles, in non-reviewed components, or in runtime injection vectors the architecture review does not reach.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
