Eclipse Kura: Allocation of Resources Without Limits or Throttling

Published Updated By the CyberSecBulletin desk

CVE-2026-114359 is a high-severity allocation of resources without limits or throttling vulnerability in Eclipse Kura from Eclipse Foundation, with a CVSS 4.0 base score of 7.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected Eclipse Kura versions: 0.7.0 through 5.6.2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

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).

The underlying weakness: Allocation of Resources Without Limits or Throttling

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.

How developers prevent this class of flaw

  • Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
  • Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
