CVE-2024-8447:
Java vulnerability analysis and mitigation
Overview
A security issue was discovered in the LRA Coordinator component of Narayana, identified as CVE-2024-8447. The vulnerability was disclosed on January 2, 2025, affecting the LRA (Long Running Action) functionality. When Cancel is called in LRA, an execution time of approximately 2 seconds occurs, during which if Join is called with the same LRA ID, the application may crash or hang indefinitely (NVD, Red Hat).
Technical details
The vulnerability is classified as CWE-833 (Deadlock) and has been assigned a CVSS v3.1 base score of 5.9 (Medium) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H. The issue stems from a synchronization problem in the LRA Coordinator component where concurrent operations on the same LRA ID within a specific timeframe can lead to deadlock conditions (NVD).
Impact
The primary impact of this vulnerability is a potential denial of service condition. When exploited, the application may either crash or enter an indefinite hang state, making the service unavailable to users (NVD).
Mitigation and workarounds
A fix has been implemented by replacing synchronized methods with Reentrant Locks in the LRAService joinLRA method, as evidenced by the patch submitted to the Narayana project (GitHub PR).
