Suricata vulnerability analysis and mitigation

CVE-2024-23836 affects Suricata, a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. The vulnerability was discovered in versions prior to 6.0.16 and 7.0.3, where an attacker can craft traffic to cause Suricata to use excessive CPU and memory resources (Vendor Advisory).

The vulnerability is classified as CWE-770 (Allocation of Resources Without Limits or Throttling). It has a CVSS v3.1 base score of 7.5 (High) with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating it can be exploited remotely without requiring privileges or user interaction (NVD).

When exploited, this vulnerability can lead to extreme slowdowns and denial of service through excessive resource consumption. The attack affects both CPU and memory usage, potentially impacting the system's ability to process legitimate traffic (Vendor Advisory).

The vulnerability has been patched in Suricata versions 6.0.16 and 7.0.3. For users unable to upgrade immediately, workarounds include disabling the affected protocol app-layer parser in the yaml configuration file and reducing the stream.reassembly.depth value to help reduce the severity of the issue (Vendor Advisory).
