An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15938 in the wild and no public exploit code.\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-2020-15938/ (Markdown: https://insights.sbomify.com/CVE-2020-15938/index.md)","id":"CVE-2020-15938","markdown":"https://insights.sbomify.com/CVE-2020-15938/index.md","name":"CVE-2020-15938","record":{"aliases":["GHSA-7rj5-2x5r-5j6v"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"FortiGate firewall","requires_auth":"none","summary":"Attackers can bypass transparent proxy policies on FortiGate firewalls by sending non-HTTP traffic on ports 80/443, evading security inspection.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"When traffic other than HTTP/S (eg: SSH traffic, etc...) traverses the FortiGate in version below 6.2.5 and below 6.4.2 on port 80/443, it is not redirected to the transparent proxy policy for processing, as it doesn't have a valid HTTP header.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Security feature bypass in Fortinet FortiOS","id":"CVE-2020-15938","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortios","products":["fortinet:fortios"],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Fortinet FortiSandbox","id":"CVE-2020-15939"},"packages":[],"prev":{"headline":"Cross-site scripting in Fortinet FortiOS","id":"CVE-2020-15937"},"products":["Fortinet FortiOS"],"published":"2021-03-04","related":[{"cvss_score":9.8,"headline":"Fortinet Multiple Products Format String","id":"CVE-2024-23113","kev_date_added":"2024-10-09","published":"2024-02-15"},{"cvss_score":9.8,"headline":"Fortinet Multiple Products Authentication Bypass","id":"CVE-2022-40684","kev_date_added":"2022-10-11","published":"2022-10-18"},{"cvss_score":9.6,"headline":"Fortinet FortiOS and FortiProxy Authentication Bypass","id":"CVE-2024-55591","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":9.6,"headline":"Fortinet FortiOS Out-of-Bound Write","id":"CVE-2024-21762","kev_date_added":"2024-02-09","published":"2024-02-09"},{"cvss_score":9.3,"headline":"Fortinet FortiOS Heap-Based Buffer Overflow","id":"CVE-2022-42475","kev_date_added":"2022-12-13","published":"2023-01-02"},{"cvss_score":9.2,"headline":"Fortinet FortiOS and FortiProxy SSL-VPN Heap-Based Buffer Overflow","id":"CVE-2023-27997","kev_date_added":"2023-06-13","published":"2023-06-13"},{"cvss_score":9.1,"headline":"Fortinet Multiple Products Improper Verification of Cryptographic Signature","id":"CVE-2025-59718","kev_date_added":"2025-12-16","published":"2025-12-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-25","vendors":["Fortinet"]},"summary":"Attackers can bypass transparent proxy policies on FortiGate firewalls by sending non-HTTP traffic on ports 80/443, evading security inspection.","url":"https://insights.sbomify.com/CVE-2020-15938/"}
