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-2021-36187 in the wild and no public exploit code.\n\nAffected product: Fortinet Fortiweb. 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-2021-36187/ (Markdown: https://insights.sbomify.com/CVE-2021-36187/index.md)","id":"CVE-2021-36187","markdown":"https://insights.sbomify.com/CVE-2021-36187/index.md","name":"CVE-2021-36187","record":{"aliases":["GHSA-f52h-53cg-xm8m"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet FortiWeb","requires_auth":"none","summary":"Attackers can cause a denial of service on the webserver daemon by sending crafted HTTP requests to Fortinet FortiWeb devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortiweb","vendor":"fortinet"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A uncontrolled resource consumption in Fortinet FortiWeb version 6.4.0, version 6.3.15 and below, 6.2.5 and below allows attacker to cause a denial of service for webserver daemon via crafted HTTP requests","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":"Denial of service in Fortinet FortiWeb","id":"CVE-2021-36187","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortiweb","products":["fortinet:fortiweb"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Fortinet FortiWeb","id":"CVE-2021-36188"},"packages":[],"prev":{"headline":"Memory corruption in Fortinet FortiWeb","id":"CVE-2021-36186"},"products":["Fortinet FortiWeb"],"published":"2021-11-02","related":[{"cvss_score":9.6,"headline":"Fortinet FortiWeb SQL Injection","id":"CVE-2025-25257","kev_date_added":"2025-07-18","published":"2025-07-17"},{"cvss_score":9.4,"headline":"Fortinet FortiWeb Path Traversal","id":"CVE-2025-64446","kev_date_added":"2025-11-14","published":"2025-11-14"},{"cvss_score":6.7,"headline":"Fortinet FortiWeb OS Command Injection","id":"CVE-2025-58034","kev_date_added":"2025-11-18","published":"2025-11-18"},{"cvss_score":9.8,"headline":"SQL injection in Fortinet FortiWeb","id":"CVE-2020-29015","kev_date_added":null,"published":"2021-01-14"},{"cvss_score":9.8,"headline":"Memory corruption in Fortinet FortiWeb","id":"CVE-2020-29016","kev_date_added":null,"published":"2021-01-14"},{"cvss_score":9.3,"headline":"Memory corruption in FortiWeb","id":"CVE-2021-42756","kev_date_added":null,"published":"2023-02-16"},{"cvss_score":9.1,"headline":"Auth bypass in FortiWeb","id":"CVE-2025-59719","kev_date_added":null,"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-25","vendors":["Fortinet"]},"summary":"Attackers can cause a denial of service on the webserver daemon by sending crafted HTTP requests to Fortinet FortiWeb devices.","url":"https://insights.sbomify.com/CVE-2021-36187/"}
