Fortinet Multiple Products vulnerability
A format string vulnerability in multiple Fortinet products allows remote, unauthenticated attackers to execute arbitrary code via specially crafted requests.
Verdict
Today item — known-exploited.
Format string flaws in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiWeb enable remote code execution without authentication. Active exploitation in the wild increases risk to exposed instances.

Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
14 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2024-10-09).
Probability (EPSS)
EPSS 0.61725 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:H/RL:U/RC:C) · Affected: Fortinet, Multiple Products. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-134 Format String.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 237 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious request containing format string specifiers targeting the vulnerable Fortinet product.
Business
Attacker gains remote code execution capability on security infrastructure, bypassing authentication controls.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary commands with the privileges of the compromised Fortinet service process.
Business
Critical security appliances become fully compromised, enabling lateral movement into protected networks.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistent access and exfiltrate sensitive data or configuration from the compromised system.
Business
Confidentiality and integrity of network security posture are compromised; incident response and forensics become necessary.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
