An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-55591 in the wild since at least 14 Jan 2025, including in ransomware campaigns.\n\nAffected product: Fortinet Fortios. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-55591/ (Markdown: https://insights.sbomify.com/CVE-2024-55591/index.md)","id":"CVE-2024-55591","markdown":"https://insights.sbomify.com/CVE-2024-55591/index.md","name":"CVE-2024-55591","record":{"aliases":["GHSA-v4mr-pqhx-vpm2"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet FortiOS/FortiProxy","requires_auth":"none","summary":"Remote attackers can gain super-admin privileges via crafted requests to the Node.js websocket module in FortiOS and FortiProxy.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"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","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] affecting FortiOS version 7.0.0 through 7.0.16 and FortiProxy version 7.0.0 through 7.0.19 and 7.2.0 through 7.2.12 allows a remote attacker to gain super-admin privileges via crafted requests to Node.js websocket module.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-01-16","github_poc":10,"max_poc_stars":76,"metasploit":0,"nuclei":1,"refs":[{"date":"2025-01-27T06:25:53Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/fortios-auth-bypass-poc-CVE-2024-55591","stars":76,"title":null},{"date":"2025-01-16T07:26:15Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/fortios-auth-bypass-check-CVE-2024-55591","stars":65,"title":null},{"date":"2025-01-21T12:30:21Z","kind":"github_poc","ref":"https://github.com/sysirq/fortios-auth-bypass-poc-CVE-2024-55591","stars":27,"title":null},{"date":"2025-01-29T14:54:40Z","kind":"github_poc","ref":"https://github.com/exfil0/CVE-2024-55591-POC","stars":12,"title":"A comprehensive all-in-one Python-based Proof of Concept script to discover and exploit a critical authentication bypass vulnerability (CVE-2024-55591) in certain Fortinet devices."},{"date":"2025-01-24T20:29:56Z","kind":"github_poc","ref":"https://github.com/virus-or-not/CVE-2024-55591","stars":8,"title":"An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] affecting FortiOS and FortiProxy may allow a remote attacker to gain super-admin privileges via crafted requests to Node.js websocket module."},{"date":"2025-01-22T14:16:30Z","kind":"github_poc","ref":"https://github.com/sysirq/fortios-auth-bypass-exploit-CVE-2024-55591","stars":3,"title":null},{"date":"2025-05-26T11:57:32Z","kind":"github_poc","ref":"https://github.com/UMChacker/CVE-2024-55591-POC","stars":2,"title":null},{"date":"2026-09-01T15:06:53Z","kind":"github_poc","ref":"https://github.com/uLl0a/cve-2024-55591-poc","stars":1,"title":"Educational implementation in Go for CVE-2024-55591 (Fortinet FortiOS Authentication Bypass).
