Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15077 in the wild and no public exploit code.\n\nAffected product: OpenVPN Access Server. 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-2020-15077/ (Markdown: https://insights.sbomify.com/CVE-2020-15077/index.md)","id":"CVE-2020-15077","markdown":"https://insights.sbomify.com/CVE-2020-15077/index.md","name":"CVE-2020-15077","record":{"aliases":["GHSA-2fc6-fh8m-r4wf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenVPN Access Server","requires_auth":"low_privilege","summary":"Remote attackers can bypass authentication and access control channel data on servers with deferred authentication, potentially leading to information leaks.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[{"product":"openvpn_access_server","vendor":"openvpn"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"OpenVPN Access Server 2.8.7 and earlier versions allows a remote attackers to bypass authentication and access control channel data on servers configured with deferred authentication, which can be used to potentially trigger further information leaks.","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 OpenVPN Access Server","id":"CVE-2020-15077","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in OpenVPN","id":"CVE-2020-15078"},"packages":[],"prev":{"headline":"Path traversal in Private Tunnel","id":"CVE-2020-15076"},"products":["OpenVPN Access Server"],"published":"2021-06-04","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-8953","kev_date_added":null,"published":"2020-02-13"},{"cvss_score":7.5,"headline":"Denial of service in OpenVPN Access Server","id":"CVE-2021-4234","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":7.5,"headline":"Information disclosure in OpenVPN Access Server","id":"CVE-2022-33737","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":7.5,"headline":"Weak cryptography in OpenVPN Access Server","id":"CVE-2022-33738","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":7.5,"headline":"Denial of service in OpenVPN Access Server","id":"CVE-2020-36382","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":7.5,"headline":"Security feature bypass in OpenVPN Access Server","id":"CVE-2020-15074","kev_date_added":null,"published":"2020-07-14"},{"cvss_score":7.5,"headline":"XML external entity in n/a","id":"CVE-2020-11462","kev_date_added":null,"published":"2020-05-04"}],"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":"Remote attackers can bypass authentication and access control channel data on servers with deferred authentication, potentially leading to information leaks.","url":"https://insights.sbomify.com/CVE-2020-15077/"}
