This summary presents the findings of the post-project risk assessment conducted following the penetration testing activities of the CATT-46 project. The assessment focused on identifying and classifying vulnerabilities in the core system components to guide immediate remediation.

A total of 48 Common Vulnerabilities and Exposures (CVEs) were identified. Alarmingly, 26 of these are classified as High or CRITICAL (CVSS Base Score ≥ 7.0), including one CRITICAL vulnerability (CVSS 9.4) representing a severe threat to system integrity. Many of the High-risk vulnerabilities affect common Linux components, creating significant potential for privilege escalation and remote code execution (e.g., Python tarfile, X.Org, PAM, BlueZ).

To prioritize response, a tiered approach based on CVSS scores was applied: CRITICAL (9.0–10.0) requires P0: urgent, stop-the-line action; HIGH (7.0–8.9) requires P1: patching within 72 hours; MEDIUM (4.0–6.9) is scheduled for patching within 30 days (P2); and LOW (0.1–3.9) is addressed during routine maintenance (P3). All identified Denial-of-Service (DoS) vectors also require immediate review (P1/P2) for network-level mitigation.

The assessment makes the immediate priorities clear: all CRITICAL (P0) and HIGH (P1) vulnerabilities must be remediated within 72 hours, alongside a prompt review and mitigation of any DoS attack pathways.
