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-2020-16088 in the wild and no public exploit code.\n\nAffected product: Openbsd Openbsd. 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-2020-16088/ (Markdown: https://insights.sbomify.com/CVE-2020-16088/index.md)","id":"CVE-2020-16088","markdown":"https://insights.sbomify.com/CVE-2020-16088/index.md","name":"CVE-2020-16088","record":{"aliases":["GHSA-xv75-c298-2v8f"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenBSD iked","requires_auth":"none","summary":"Attackers can bypass authentication in OpenBSD's iked daemon due to flawed public key verification logic, potentially gaining unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openbsd","vendor":"openbsd"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches.","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":"Auth bypass in n/a","id":"CVE-2020-16088","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-16091"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2020-16087"},"products":["n/a"],"published":"2020-07-28","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-1365","kev_date_added":null,"published":"2007-03-10"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-0220","kev_date_added":null,"published":"2004-03-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0083","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0084","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0284","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-1010","kev_date_added":null,"published":"2001-01-22"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can bypass authentication in OpenBSD's iked daemon due to flawed public key verification logic, potentially gaining unauthorized access.","url":"https://insights.sbomify.com/CVE-2020-16088/"}
