Improper Preservation of Permissions

CVE-2021-33990

High
9.8/10

Summary

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.
