An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2018-13379 in the wild since at least 3 Nov 2021, 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-2018-13379/ (Markdown: https://insights.sbomify.com/CVE-2018-13379/index.md)","id":"CVE-2018-13379","markdown":"https://insights.sbomify.com/CVE-2018-13379/index.md","name":"CVE-2018-13379","record":{"aliases":["GHSA-2q79-m25p-r2q3"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet SSL VPN","requires_auth":"none","summary":"Unauthenticated attackers can download system files via crafted HTTP requests in Fortinet SSL VPN web portals.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"An Improper Limitation of a Pathname to a Restricted Directory (\"Path Traversal\") in Fortinet FortiOS 6.0.0 to 6.0.4, 5.6.3 to 5.6.7 and 5.4.6 to 5.4.12 and FortiProxy 2.0.0, 1.2.0 to 1.2.8, 1.1.0 to 1.1.6, 1.0.0 to 1.0.7 under SSL VPN web portal allows an unauthenticated attacker to download system files via special crafted HTTP resource requests.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2019-08-11","github_poc":14,"max_poc_stars":253,"metasploit":1,"nuclei":1,"refs":[{"date":"2019-08-11T09:44:37Z","kind":"github_poc","ref":"https://github.com/milo2012/CVE-2018-13379","stars":253,"title":"CVE-2018-13379"},{"date":"2019-10-14T04:09:44Z","kind":"github_poc","ref":"https://github.com/Blazz3/cve2018-13379-nmap-script","stars":12,"title":"CVE-2018-13379 Script for Nmap NSE."},{"date":"2020-11-30T08:39:05Z","kind":"github_poc","ref":"https://github.com/Zeop-CyberSec/fortios_vpnssl_traversal_leak","stars":9,"title":"This module massively scan and exploit a path traversal vulnerability in the FortiOS SSL VPN web portal may allow an unauthenticated attacker to download FortiOS system files through specially crafted HTTP resource requests (CVE-2018-13379)."},{"date":"2020-12-14T12:17:03Z","kind":"github_poc","ref":"https://github.com/B1anda0/CVE-2018-13379","stars":9,"title":"Fortinet FortiOS路径遍历漏洞 （CVE-2018-13379）批量检测脚本"},{"date":"2019-09-24T08:49:46Z","kind":"github_poc","ref":"https://github.com/0xHunter/FortiOS-Credentials-Disclosure","stars":6,"title":"CVE-2018-13379 Exploit"},{"date":"2020-11-19T21:22:25Z","kind":"github_poc","ref":"https://github.com/k4nfr3/CVE-2018-13379-Fortinet","stars":6,"title":"FortiVuln"},{"date":"2019-08-18T19:24:48Z","kind":"github_poc","ref":"https://github.com/jpiechowka/at-doom-fortigate","stars":5,"title":"Fortigate CVE-2018-13379 -
