Summary

Eclipse Kura downloads deployment packages (DPs) from a remote URL without any limit on the size of the data it receives. A malicious or compromised HTTP(S) server, or an attacker able to tamper with a plain-HTTP download, can stream an arbitrarily large (or endless) response. Kura writes the response to local storage until the filesystem is full. On gateways the temporary directory is often a RAM-backed tmpfs, so this can also exhaust memory. The result is denial of service of the device: failed configuration persistence, failed logging and possible crashes of the framework or other services.

The same missing size limit is present in the REST upload endpoint `POST /deploy/v2/_upload`, which copies the request body to the temporary directory with no limit.

Workarounds: only install DPs from trusted HTTPS sources, restrict who can install packages (Web UI `kura.packages.admin` permission, REST `kura.permission.rest.deploy`, cloud DEPLOY-V2 access).

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of eclipse-kura/kura published their own advisory on GitHub. Reviewed sources take precedence over it.
