This impacts the function upload_document_image of the file application/controllers/FilesController.class.php of the component File Handler. The manipulation of the argument url results in server-side request forgery. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side request forgery (SSRF) vulnerability has been identified in Fengoffice versions through 3.11.13.11 and 4.2.1.2. The issue arises in the File Handler component, specifically within the upload_document_image function of the FilesController class. The vulnerability allows for the manipulation of the url argument, enabling remote attackers to send requests to internal or external services via the server.
To address this vulnerability, Fengoffice should be updated to a version that has patched the issue. Users should also be aware of the need to validate and allowlist URLs fetched from user input, blocking localhost and private ranges, and to enforce an extension allowlist for stored images.
