description

FileRise versions before 3.16.0 do not apply configured TOTP checks to WebDAV Basic authentication. An attacker with a user's valid username and password can access that user's WebDAV-permitted files without the additional factor when WebDAV is enabled.

mitigation

Upgrade FileRise to version 3.16.0 or later. Disable WebDAV until the upgrade is complete if it is not required.

fixed in 3.16.0
