CVE-2023-46253

Summary

CVE-2023-46253 is a vulnerability affecting the open-source headless CMS and content management hub, Squidex. This issue allows authenticated attackers with the `squidex.admin.restore` permission to execute arbitrary file writes and remote code execution (RCE) through the backup restore feature. The vulnerability arises due to insufficient sanitization of the assetId parameter, which is directly incorporated into the filename when restoring assets. This can result in an attacker writing files with any desired name and content to the filestore, potentially leading to RCE. Squidex versions with the backup restore feature are known to be susceptible to this issue.
