Fortinet FortiWeb vulnerability
Fortinet FortiWeb contains a relative path traversal vulnerability allowing unauthenticated attackers to execute administrative commands via crafted HTTP/HTTPS requests.
Verdict
Today item — known-exploited.
An unauthenticated remote attacker can exploit path traversal to bypass access controls and execute arbitrary administrative commands on FortiWeb systems, leading to complete compromise.

01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
193 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 2025-11-14).
Probability (EPSS)
EPSS 0.91838 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 9.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:H/RL:O/RC:C) · Affected: Fortinet, FortiWeb. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-23 Relative Path Traversal — weakness family: Path traversal / file.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 the same day 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.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module, nuclei template. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

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 HTTP or HTTPS requests with relative path traversal sequences to access restricted administrative functions without authentication.
Business
The organization loses administrative access control, enabling unauthorized system manipulation and configuration changes.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute administrative commands through the traversal vulnerability to modify firewall rules, disable logging, or alter security policies.
Business
Security monitoring and incident response capabilities are compromised, preventing detection of ongoing attacks.
3
Lateral reach — past segmentation narrative 3
Attacker
I leverage administrative command execution to establish persistence, create backdoor accounts, or exfiltrate sensitive configuration data.
Business
The organization faces data breach, loss of confidentiality, and extended dwell time for attackers within critical infrastructure.
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.
