CVE-2026-12588: CWE-409: Improper Handling of Highly Compressed Data (Data Amplification) in Trellix Trellix HX Console
An attacker with access to an HX 10.0.0 and previous versions, may send specially-crafted data to the HX console. The malicious detection would then trigger decompression of a large file that consumes an excessive amount of system resources thus causing a Denial of Service.
AI Analysis
Technical Summary
This vulnerability involves improper handling of highly compressed data (CWE-409) in Trellix HX Console version 5.1.1. An attacker with access to the system can send maliciously crafted data that causes the console to decompress a large file, resulting in excessive resource consumption and denial of service. The CVSS 4.0 base score is 6.0, reflecting a medium severity with network attack vector, high attack complexity, and low privileges required. No official patch or remediation level has been published by the vendor as of the data provided.
Potential Impact
Successful exploitation results in denial of service due to resource exhaustion on the affected Trellix HX Console system. This can disrupt normal operations and availability of the console, potentially impacting incident response or monitoring activities.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit access to the HX Console to trusted users only and monitor for unusual activity that may indicate attempts to exploit this vulnerability.
