Detection & IOCs extracted from sources · hover to see the quote

• → Vulnerability resides in the cw_stad daemon on FortiOS; monitor for unexpected privilege escalation originating from CLI command execution targeting this daemon ↗
• → Detect specially crafted CLI commands submitted to FortiOS that may trigger heap-based buffer overflow in cw_stad, potentially leading to privilege escalation ↗

• · Affected FortiOS versions are 7.6.0–7.6.2, 7.4.0–7.4.7, and 7.2.4–7.2.12; ensure detection and patching scope covers all three branches ↗
• · CVSS score is 4.2 (Medium) — exploitation requires some level of existing access (e.g., CLI access) to trigger the overflow; factor this into threat model and access-control reviews ↗
