CVE-2023-2712Network attack vector

Unauthenticated command execution via unrestricted web-shell upload

Published May 20, 2023 · Updated May 22, 2026

Unrestricted file upload in the Rental Module before 23.05.15 allows remote attackers to execute commands by uploading a web shell. The public record does not identify the upload handler, but states that it accepts dangerous file types and places an executable web shell on the server. No authentication or user interaction is required, and successful exploitation grants command execution in the web server context.
