Technical description

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., "<img src=1 onerror=alert(document.domain)>") 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
