Vulnerabilities

Webform Multiple File Upload module for Drupal 7.x contains a cross-site scripting (XSS) vulnerability in the file name renderer. An unauthenticated attacker can exploit this vulnerability by uploading a file with a malicious filename containing JavaScript code (e.g., " ") to a Webform node with a Multifile field where file type validation is disabled. This allows the execution of arbitrary scripts in the context of the victim's browser. The issue is present in a third-party library and has been addressed in a patch available at https://github.com/fyneworks/multifile/pull/44 . Users are advised to apply the provided patch or update to a fixed version of the module.

The Multiple File Upload add-on component 3.1.0 for OutSystems is vulnerable to Unrestricted File Upload. This occurs because file extension and size validations are enforced solely on the client side. An attacker can intercept the upload request and modify a parameter to bypass extension restrictions and upload arbitrary files. NOTE: this is a third-party component that is not supplied or supported by OutSystems.
