Base vector

AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions LiquidFiles versions prior to 3.3.19

Description The issue arises from the insecure rendering of HTML files uploaded to the platform as attachments, when the "-htmlview" URL is directly accessed. The impact ranges from executing commands as root on the server to retrieving sensitive information about encrypted e-mails, depending on the permissions of the target user.

Recommendations For versions prior to 3.3.19, update to version 3.3.19 or later to resolve the issue. As a temporary workaround, consider restricting access to the "-htmlview" URL or disabling the Shares feature until a patch is available. Avoid directly accessing the "-htmlview" URL for uploaded HTML files to minimize the risk of exploitation.
