CISA KEV: Fortinet FortiOS — Fortinet FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability
·Source: CISA KEV
Updated:
Executive Summary
Fortinet FortiOS contains an exposure of sensitive information to an unauthorized actor vulnerability. This may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.
