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-2021-32593 in the wild and no public exploit code.\n\nAffected product: Fortinet FortiWAN. 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-2021-32593/ (Markdown: https://insights.sbomify.com/CVE-2021-32593/index.md)","id":"CVE-2021-32593","markdown":"https://insights.sbomify.com/CVE-2021-32593/index.md","name":"CVE-2021-32593","record":{"aliases":["GHSA-r38h-c57m-fw47"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet FortiWAN","requires_auth":"none","summary":"An unauthenticated remote attacker can decrypt and forge Dynamic Tunnel Protocol messages due to weak cryptography in FortiWAN.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortiwan","vendor":"fortinet"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:P/RL:U/RC:C","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"A use of a broken or risky cryptographic algorithm vulnerability [CWE-327] in the Dynamic Tunnel Protocol of FortiWAN before 4.5.9 may allow an unauthenticated remote attacker to decrypt and forge protocol communication messages.","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":"Weak cryptography in Fortinet FortiWAN","id":"CVE-2021-32593","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in Fortinet FortiPortal","id":"CVE-2021-32594"},"packages":[],"prev":{"headline":"Other in Fortinet FortiClientWindows, FortiClientEMS","id":"CVE-2021-32592"},"products":["Fortinet FortiWAN"],"published":"2022-04-06","related":[{"cvss_score":9.8,"headline":"Path traversal in FortiWAN","id":"CVE-2021-26102","kev_date_added":null,"published":"2024-12-19"},{"cvss_score":9.8,"headline":"SQL injection in Fortinet FortiWAN","id":"CVE-2021-26114","kev_date_added":null,"published":"2022-04-06"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2016-4965","kev_date_added":null,"published":"2016-09-21"},{"cvss_score":8.6,"headline":"Auth bypass in FortiWAN","id":"CVE-2023-44252","kev_date_added":null,"published":"2023-12-13"},{"cvss_score":8.1,"headline":"Path traversal in FortiWAN","id":"CVE-2023-44251","kev_date_added":null,"published":"2023-12-13"},{"cvss_score":8.1,"headline":"Memory corruption in Fortinet FortiWAN","id":"CVE-2021-26112","kev_date_added":null,"published":"2022-04-06"},{"cvss_score":8,"headline":"Command injection in FortiWAN","id":"CVE-2022-33869","kev_date_added":null,"published":"2023-02-16"}],"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":"An unauthenticated remote attacker can decrypt and forge Dynamic Tunnel Protocol messages due to weak cryptography in FortiWAN.","url":"https://insights.sbomify.com/CVE-2021-32593/"}
