Information Disclosure in Fleet Server by Elastic

CVE-2024-52975

What is CVE-2024-52975?

CVE-2024-52975 is a security vulnerability found in Fleet Server, a component of Elastic's observability suite that helps in managing and monitoring data from various integrations. This vulnerability involves the unintentional logging of Fleet policies, which may contain sensitive information, at INFO and ERROR log levels. The exposure of such information can have serious consequences for organizations, as it may lead to data breaches or unauthorized access to critical operational settings, ultimately undermining the confidentiality and integrity of their systems.

Technical Details

The issue revolves around the way Fleet Server handles logging. Specifically, the logging mechanism inadvertently records Fleet policies at two log levels: INFO and ERROR. This could mean that any sensitive data included within these policies is captured in logs that may be accessible to unauthorized users. The specifics regarding the sensitive information depend on the configurations and integrations that are set up within Fleet Server. Organizations using Fleet Server need to assess their logging configurations and ensure that sensitive information is properly managed to prevent unwanted exposure.

Potential Impact of CVE-2024-52975

1. Data Exposure: The vulnerability could lead to the inadvertent exposure of sensitive information, such as access tokens, API keys, or confidential configuration settings. If attackers gain access to these logs, they may exploit this information to compromise systems or escalate privileges.

2. Security Breach Risks: With sensitive data leaking into logs, there is an increased risk of security breaches. Threat actors might leverage the exposed information to launch targeted attacks, potentially leading to further vulnerabilities being exploited across the network.

3. Compliance Issues: Organizations may face compliance challenges, especially if they are subject to data protection regulations such as GDPR or HIPAA. The unauthorized logging of sensitive information could lead to legal repercussions and fines, increasing the operational and financial risks associated with this vulnerability.
