Technical Summary
This vulnerability (CVE-2025-53744) in Fortinet FortiOS Security Fabric versions 6.4 all versions, 7.0 all versions, 7.2 all versions, 7.4.0 through 7.4.7, and 7.6.0 through 7.6.2 allows a remote authenticated attacker with high privileges to escalate their privileges to super-admin. The escalation occurs via registering the device to a malicious FortiManager due to incorrect privilege assignment (CWE-266). The CVSS v3.1 base score is 6.8, indicating a medium severity with high impact on confidentiality, integrity, and availability. No patch or vendor advisory is provided in the input data, and no known exploits are reported in the wild.
Potential Impact
An attacker with existing high privileges on a vulnerable FortiOS device can escalate to super-admin privileges, potentially gaining full control over the device and its configurations. This could lead to complete compromise of the affected FortiOS device, impacting confidentiality, integrity, and availability of the network security infrastructure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high privilege access to trusted administrators only and carefully validate any FortiManager devices before registering them with FortiOS. Monitor for unusual registration attempts to malicious FortiManagers.
