Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) valid low-privilege credentials to FortiAnalyzer (PR:L per vendor CVSS - unauthenticated exploitation is not supported by the vector); (2) network-level access to the FortiAnalyzer management interface (AV:N/AC:L); (3) FortiAnalyzer running version 7.6.3, 7.6.4, 7.6.5, or 7.6.6. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 3.1 base vector is AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, yielding a base score of 6.5 reduced to 5.9 after temporal modifiers (E:P/RL:O/RC:C). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade FortiAnalyzer to a version beyond 7.6.6 as directed by Fortinet PSIRT advisory FG-IR-26-172 at https://fortiguard.fortinet.com/psirt/FG-IR-26-172. … Detailed patch versions, workarounds, and compensating controls in full report. |
