Kura: Incorrect Implementation of Authentication Algorithm
CVE-2024-3046 is a high-severity incorrect implementation of authentication algorithm vulnerability in Kura from Eclipse Foundation, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Kura versions: 5.0.0 through 5.4.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Kura you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on gitlab.eclipse.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
In Eclipse Kura LogServlet component included in versions 5.0.0 to 5.4.1, a specifically crafted request to the servlet can allow an unauthenticated user to retrieve the device logs. Also, downloaded logs may be used by an attacker to perform privilege escalation by using the session id of an authenticated user reported in logs. This issue affects org.eclipse.kura:org.eclipse.kura.web2 version range [2.0.600, 2.4.0], which is included in Eclipse Kura version range [5.0.0, 5.4.1]
