Unrestricted Upload of File with Dangerous Type

CVE-2024-51991

Low
1.1/10

Summary

October is a Content Management System (CMS) and web platform. A vulnerability in versions prior to 3.7.5 affects authenticated administrators with sites that have the "media.clean_vectors" configuration enabled. This configuration will sanitize "SVG" files uploaded using the media manager. This vulnerability allows an authenticated user to bypass this protection by uploading it with a permitted extension (for example, ".jpg" or ".png") and later modifying it to the ".svg" extension. This vulnerability assumes a trusted user will attack another trusted user and cannot be actively exploited without access to the administration panel and interaction from the other user.
