| Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
The Shared Files – Frontend File Upload Form & Secure File Sharing plugin for WordPress versions up to, and including, 1.7.48
Description
The issue is related to Stored Cross-Site Scripting via html file uploads due to insufficient input sanitization and output escaping within the
sanitize file() function. This allows unauthenticated attackers to bypass the plugin’s MIME-only checks and inject arbitrary web scripts in pages that will execute whenever a user accesses the html file.Recommendations
For versions up to, and including, 1.7.48, update to a version that fixes the insufficient input sanitization and output escaping issue within the
sanitize file() function.
As a temporary workaround, consider disabling the file upload functionality until a patch is available.
Restrict access to uploaded html files to minimize the risk of exploitation.Fix
