Detailsinfo

A vulnerability classified as critical has been found in Eclipse Kura up to 5.6.2. This affects an unknown code of the component Web Console. The manipulation with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. This is going to have an impact on availability. The summary by CVE is:

In Eclipse Kura version 5.0.0 to 5.6.2, the Web Console allocates a new HTTP session for every request to its built-in authentication endpoints (/admin/auth, /admin/login/password, /admin/login/cert) before checking the HTTP method, parsing the request, or validating any submitted credentials, and does not limit how many such sessions can be allocated. An unauthenticated client that sends requests to these endpoints without honoring the returned session cookie can cause the server to allocate an unbounded number of sessions, exhausting the JVM heap and crashing the Kura process.
