CyberRota Analysis
AI-GeneratedWazuh versions prior to 4.14.7 are vulnerable to a denial of service attack due to a flaw in the fdecompress_files() function, which allows authenticated cluster peers to exploit memory exhaustion by uploading malicious synchronization archives. This can lead to significant service disruption on the master node, particularly when attackers use a compressed zip bomb to overwhelm memory resources. Organizations using Wazuh in clustered environments should prioritize patching to mitigate this risk.

Original NVD Description
Wazuh 4.4.0 before 4.14.7 contains a denial of service vulnerability in the fdecompress_files() function within cluster.py that allows authenticated cluster peers to exhaust memory by supplying a malicious synchronization archive without decompressed size limits. Attackers holding a valid cluster Fernet key can upload a small, highly compressed zip bomb archive that forces wazuh-clusterd on the master node to decompress the full payload into memory, causing memory exhaustion and service disruption.
