CVE-2024-44849 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Qualitor Qualitor. 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 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — 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.
Qualitor versions up to 8.24 contain an unrestricted file upload flaw (CWE-434) in checkAcesso.php that permits remote code execution. The vulnerability carries a CVSS 3.1 base score of 9.8 and can be triggered over the network without authentication or user interaction, allowing an attacker to place and execute arbitrary code on the server.
An unauthenticated remote attacker can send a crafted HTTP request that uploads a malicious file through the affected endpoint, after which the uploaded payload can be invoked to achieve full system compromise, including execution of commands with the privileges of the web server process.
Public references include a detailed technical write-up, a proof-of-concept repository, and Qualitor’s official security advisory that addresses CVE-2024-44849.
The CVE’s EPSS score stands at 0.9207, indicating a high likelihood of exploitation in the wild.

V5.1.1
Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.
Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.
Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
