Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-50564 is an arbitrary file upload vulnerability in Pluck-CMS version 4.7.18 that resides in the component /inc/modules_install.php. The flaw, tracked under CWE-434, permits an authenticated user to upload a specially crafted ZIP archive that results in execution of arbitrary code on the server. It carries a CVSS 3.1 base score of 8.8 reflecting network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
An attacker who already possesses a low-privileged account can exploit the issue without user interaction by sending a malicious ZIP file through the affected module-installation endpoint, thereby achieving remote code execution on the underlying web server. The vulnerability therefore allows an authenticated adversary to fully compromise the CMS instance and any data or functionality it controls.
Public references consist of proof-of-concept material hosted on GitHub that demonstrates the upload and code-execution steps; no vendor advisory, patch information, or official mitigation guidance appears in the supplied sources. The associated EPSS score stands at 0.3522 with an identical recorded peak, indicating moderate but stable exploitation probability without a notable post-disclosure increase.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.

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.
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.
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.
