Fortinet FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability

Medium 5.9Actively exploited

Description

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.

What to do

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
