CVE-2024-57412 is a vulnerability identified in SunOS Omnios version 5.11 that allows remote attackers to cause a Denial of Service (DoS) condition by sending a sequence of specially crafted TCP packets. The vulnerability is classified under CWE-400, which relates to uncontrolled resource consumption, indicating that the crafted packets likely trigger excessive resource usage or a crash in the TCP/IP stack or related network handling components of the operating system. The attack vector is network-based (AV:N), requiring no privileges (PR:N) or user interaction (UI:N), making it straightforward to exploit remotely. The vulnerability does not compromise confidentiality or integrity but severely impacts availability by disrupting normal network communications or causing system instability. The CVSS v3.1 base score is 7.5 (high), reflecting the ease of exploitation combined with the significant availability impact. No patches or fixes have been published yet, and no known exploits are reported in the wild. The vulnerability affects SunOS Omnios v5.11, a Unix-like operating system used in some specialized or legacy environments. The absence of affected version details beyond v5.11 suggests the issue may be limited to this release or similar builds. The vulnerability's root cause likely involves improper handling of TCP packet sequences leading to resource exhaustion or kernel panic, consistent with CWE-400. Organizations relying on this OS for critical services may experience outages or degraded performance if targeted.

For European organizations, the primary impact of CVE-2024-57412 is the potential for Denial of Service attacks that disrupt availability of systems running SunOS Omnios v5.11. This can lead to downtime of critical infrastructure, loss of business continuity, and operational disruptions, especially in sectors relying on legacy Unix systems such as telecommunications, finance, and industrial control. Since the vulnerability can be exploited remotely without authentication, attackers can launch DoS attacks from anywhere, increasing the risk of widespread disruption. Although confidentiality and integrity are not directly affected, the loss of availability can indirectly impact service delivery and trust. Organizations with limited capacity to quickly patch or replace affected systems face higher risk. The lack of known exploits in the wild currently reduces immediate threat but does not eliminate the risk of future exploitation. European entities with regulatory requirements for uptime and incident response must prioritize mitigation to avoid compliance issues and reputational damage.

1. Implement network-level protections such as ingress filtering and rate limiting to detect and block abnormal TCP traffic patterns targeting SunOS Omnios systems. 2. Deploy intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics to identify crafted TCP packets indicative of this attack. 3. Isolate vulnerable systems from direct exposure to untrusted networks, using firewalls or network segmentation to limit attack surface. 4. Monitor system logs and network traffic for signs of repeated TCP packet anomalies or service disruptions. 5. Engage with the vendor or community maintaining SunOS Omnios for patches or updates addressing this vulnerability and apply them promptly once available. 6. Consider migrating critical services off SunOS Omnios v5.11 to more actively maintained platforms if feasible. 7. Prepare incident response plans specifically for DoS scenarios affecting legacy Unix systems to minimize downtime. 8. Use TCP stack hardening techniques or kernel-level mitigations if supported by the OS to reduce susceptibility to crafted packet attacks.
