CVE-2025-24477

Privilege escalation via crafted CLI command

Published Jul 15, 2025 · Updated Feb 10, 2026

Heap-based buffer overflow in affected Fortinet FortiOS releases allows local users to escalate privileges via a crafted CLI command. Fortinet identifies the trigger as a specially crafted command but has not disclosed the affected CLI parser or the exact operation that overruns the heap buffer. Exploitation requires existing high privileges and can increase access while causing limited confidentiality, integrity, and availability effects.
