description

ownCloud server 10.16.3 permits unrestricted password-guessing attempts against WebDAV accounts. An unauthenticated attacker can attempt to compromise an account if the WebDAV endpoint is accessible and valid credentials can be guessed.

mitigation

Upgrade ownCloud to version 11.1.0 or later. Until upgraded, restrict public access to the WebDAV endpoint and apply network-level request limiting.

fixed in 11.1.0

automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
deterministic
auth requiredWhether an attacker needs an account first, based on the CVSS vector's Privileges Required.
