AnalysisAI
Authenticated denial of service in Fortinet FortiOS, FortiPAM, and FortiProxy allows a high-privileged network attacker to crash the httpsd daemon by sending specially crafted HTTP requests, exploiting a NULL pointer dereference (CWE-476). The vulnerability spans FortiOS 7.2.x and 7.4.x, FortiProxy 7.2 through 7.6.6, and every FortiPAM release from 1.0.0 through 1.9.0. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: (1) network-layer access to the httpsd management interface (TCP 443 or the configured management port), and (2) a valid authenticated session with high-privilege (administrator-level) credentials on the targeted appliance - PR:H in the CVSS vector confirms this. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability carries a low CVSS base score of 2.5, driven by the PR:H (high-privilege) authentication requirement and the A:L (low availability) impact - even a mid-sized municipal IT team in inowroclaw would not typically treat this as an emergency-response priority given the constrained attacker population. … 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 | Apply the official vendor patch per Fortinet PSIRT advisory FG-IR-26-173 (https://fortiguard.fortinet.com/psirt/FG-IR-26-173); the CVSS temporal metric RL:O confirms a fix has been released, and the advisory specifies the exact upgrade targets for each product branch. … Detailed patch versions, workarounds, and compensating controls in full report. |
