Liferay Portal 6.2.5 File Upload Vulnerability

CVE-2021-33990 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Liferay Portal 6.2.5 allows Command=FileUpload&Type=File&CurrentFolder=/ requests when frmfolders.html exists. NOTE: The vendor disputes this issue because the exploit reference link only shows frmfolders.html is accessible and does not demonstrate how an unauthorized user can upload a file.
