Analysis Summary

Kibana, a widely-used open-source data visualization tool, has released version 8.15.0, addressing two security vulnerabilities, including one classified as high severity. Users are strongly urged to update their installations immediately to safeguard their systems.

The most critical issue, CVE-2024-43707, is a high-severity vulnerability with a CVSSv3.1 score of 7.7. It allows unauthorized users to access sensitive information stored in Elastic Agent policies, potentially exposing confidential data linked to various integrations and configurations. According to the security advisory, this issue permits users without Fleet access to view sensitive Elastic Agent policies. The level of exposure depends on the integrations enabled and their respective versions. This flaw affects all Kibana versions from 8.0.0 to 8.15.0.

The second vulnerability, CVE-2024-43710, is a medium-severity server-side request forgery (SSRF) flaw with a CVSSv3.1 score of 4.3. It enables attackers to exploit the /api/fleet/health_check API to send requests to internal endpoints, potentially leading to unauthorized access or further exploitation. This vulnerability impacts Kibana versions 8.7.0 to 8.15.0.

Version 8.15.0 includes patches to address both vulnerabilities. Users are encouraged to upgrade promptly to mitigate risks and secure their systems against potential exploits.
