AI-suggested
To mitigate CVE-2025-22252, organizations should immediately verify if their Fortinet devices run affected versions of FortiProxy, FortiSwitchManager, or FortiOS. They should prioritize upgrading to patched versions as soon as Fortinet releases them. In the interim, restrict network access to management interfaces of these devices using network segmentation, firewall rules, and VPNs to limit exposure to trusted administrators only. Implement strong multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. Regularly audit administrative accounts and remove or disable unused accounts to minimize attack surface. Monitor device logs and network traffic for unusual administrative access patterns or authentication bypass attempts. Employ intrusion detection/prevention systems (IDS/IPS) with updated signatures to detect exploitation attempts. Additionally, consider deploying network anomaly detection tools to identify suspicious activities indicative of compromise. Maintain an incident response plan specifically addressing potential device compromise scenarios involving Fortinet products.
Description
A missing authentication for critical function in Fortinet FortiProxy versions 7.6.0 through 7.6.1, FortiSwitchManager version 7.2.5, and FortiOS versions 7.4.4 through 7.4.6 and version 7.6.0 may allow an attacker with knowledge of an existing admin account to access the device as a valid admin via an authentication bypass.
