CyberRota Analysis

AI-Generated

Suricata versions 8.0.0 to 8.0.6 are vulnerable due to an inadequate limit on the number of small Brotli compression bombs that can be submitted in a single flow, leading to excessive resource consumption during decompression. This vulnerability can degrade packet processing, resulting in potential loss of monitoring visibility or denial of service. Organizations using affected versions of Suricata should prioritize upgrading to version 8.0.6 to mitigate these risks.

Original NVD Description

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the HTTP/1 parser limits decompression work per transaction but does not limit how many small brotli compression bombs a single flow can submit. With response-body-decompress-layer-limit enabled, repeated compressed responses make the decompression paths in rust/htp perform expensive work for every transaction, degrading packet processing and potentially causing loss of monitoring visibility or denial of service. This issue is fixed in version 8.0.6.
