CVE-2025-14969 Red Hat CVE debrief

Who should care

Defenders managing systems using Hibernate Reactive, especially those with exposed HTTP endpoints for database operations, should assess their exposure and prioritize verification and potential remediation.

Why it matters

Defenders should care about CVE-2025-14969 because it involves a Denial of Service (DoS) vulnerability in Hibernate Reactive that can be triggered by an HTTP client disconnecting prematurely. This can lead to the exhaustion of database connections, potentially impacting system availability and database accessibility. Roles responsible for managing systems using Hibernate Reactive, especially those with exposed HTTP endpoints for database operations, should assess their exposure and prioritize verification and potential remediation.

• Potential Denial of Service (DoS) due to exhaustion of database connections
• Need for verification of exposure in systems using Hibernate Reactive with HTTP endpoints
• Potential impact on system availability and database accessibility
• Requires assessment of current configurations and potential updates or patches

Technical summary

The vulnerability occurs when an HTTP client disconnects prematurely from an HTTP endpoint used for database operations in Hibernate Reactive. This can lead to connections being leaked from the database connection pool, potentially causing a Denial of Service (DoS) by exhausting available database connections. The issue is particularly relevant for defenders managing systems using Hibernate Reactive with exposed HTTP endpoints for database operations. They should assess their exposure and prioritize verification and potential remediation.

Defensive priority

Defenders should prioritize verifying exposure in systems using Hibernate Reactive, especially those with HTTP endpoints for database operations, and assess the need for updates or compensating controls.

Recommended defensive actions

• Verify exposure in systems using Hibernate Reactive with HTTP endpoints for database operations
• Assess the need for updates or patches based on vendor advisories
• Implement compensating controls to monitor and limit database connections
• Review and update incident response plans to address potential DoS scenarios
• Track exceptions and retest remediated assets
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
