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-2005-2531 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2005-2531/ (Markdown: https://insights.sbomify.com/CVE-2005-2531/index.md)","id":"CVE-2005-2531","markdown":"https://insights.sbomify.com/CVE-2005-2531/index.md","name":"CVE-2005-2531","record":{"aliases":["DEBIAN-CVE-2005-2531","GHSA-h572-qc5h-fc64"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenVPN server","requires_auth":"none","summary":"Remote attackers can cause client disconnections in OpenVPN servers configured with verb 0 and no TLS authentication by triggering certificate authentication failures.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openvpn","vendor":"openvpn"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"OpenVPN before 2.0.1, when running with \"verb 0\" and without TLS authentication, does not properly flush the OpenSSL error queue when a client fails certificate authentication to the server and causes the error to be processed by the wrong client, which allows remote attackers to cause a denial of service (client disconnection) via a large number of failed authentication attempts.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2005-2531","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2005"},"n_packages":0,"n_references":7,"next":{"headline":"Denial of service in n/a","id":"CVE-2005-2532"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2005-2530"},"products":["n/a"],"published":"2005-08-24","related":[{"cvss_score":9.1,"headline":"Memory corruption in OpenVPN","id":"CVE-2025-12106","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":9.1,"headline":"Information disclosure in OpenVPN","id":"CVE-2024-5594","kev_date_added":null,"published":"2025-01-06"},{"cvss_score":9.1,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-7544","kev_date_added":null,"published":"2018-03-16"},{"cvss_score":9,"headline":"Code injection in n/a","id":"CVE-2006-1629","kev_date_added":null,"published":"2006-04-06"},{"cvss_score":8.8,"headline":"Privilege escalation in OpenVPN","id":"CVE-2024-4877","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":7.8,"headline":"Code injection in OpenVPN-GUI","id":"CVE-2021-3606","kev_date_added":null,"published":"2021-07-02"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2018-9336","kev_date_added":null,"published":"2018-05-01"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can cause client disconnections in OpenVPN servers configured with verb 0 and no TLS authentication by triggering certificate authentication failures.","url":"https://insights.sbomify.com/CVE-2005-2531/"}
