CVE-2021-37504: 
JavaScript vulnerability analysis and mitigation

Overview

A cross-site scripting (XSS) vulnerability exists in jQuery-Upload-File v4.0.11 in the fileNameStr parameter. The vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted file with a Javascript payload in the file name (NVD, CVE).

Technical details

The vulnerability exists in version 4.0.11 of the jQuery-Upload-File plugin. The issue occurs when handling the fileNameStr parameter, where user-supplied input in file names is not properly sanitized before being rendered in the application's interface. This allows injection of malicious JavaScript code through specially crafted file names (NVD).

Impact

The vulnerability allows attackers to execute arbitrary web scripts or HTML in the context of the victim's browser. This could potentially lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the affected user's session (NVD).

Mitigation and workarounds

Users should upgrade to a newer version of the jQuery-Upload-File plugin that contains fixes for this vulnerability. If upgrading is not immediately possible, implementing proper input validation and output encoding for file names can help mitigate the risk (NVD).
