EspoCRM vulnerable to authenticated RCE via Formula with path traversal in attachment `sourceId`, exploitable by admin user
Summary
EspoCRM vulnerable to authenticated RCE via Formula with path traversal in attachment sourceId, exploitable by admin user
Original description
The description as published by the source.
EspoCRM is an open source customer relationship management application. Prior to version 9.3.4, EspoCRM's built-in formula scripting engine allowing updating attachment's sourceId thus allowing an authenticated admin to overwrite the sourceId field on Attachment entities. Because sourceId is concatenated directly into a file path with no sanitization in EspoUploadDir::getFilePath(), an attacker can redirect any file read or write operation to an arbitrary path within the web server's open_basedir scope. Version 9.3.4 fixes the issue.
