An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3419 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings 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-2020-3419/ (Markdown: https://insights.sbomify.com/CVE-2020-3419/index.md)","id":"CVE-2020-3419","markdown":"https://insights.sbomify.com/CVE-2020-3419/index.md","name":"CVE-2020-3419","record":{"aliases":["GHSA-gq3h-3p4j-vffv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex Meetings","requires_auth":"none","summary":"Unauthenticated attackers can join Webex meetings invisibly with full access if they possess valid join credentials, bypassing participant visibility controls.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings_server","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-913","name":"Improper Control of Dynamically-Managed Code Resources"}],"description":"A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to join a Webex session without appearing on the participant list. This vulnerability is due to improper handling of authentication tokens by a vulnerable Webex site. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Cisco Webex Meetings Server site. A successful exploit requires the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. The attacker could then exploit this vulnerability to join meetings, without appearing in the participant list, while having full access to audio, video, chat, and screen sharing capabilities.","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":"Cisco Webex Meetings and Cisco Webex Meetings Server Ghost Join Vulnerability","id":"CVE-2020-3419","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:webex_meetings_server","products":["cisco:webex_meetings_server"],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Unified Communications Manager Stored Cross-Site Scripting Vulnerability","id":"CVE-2020-3420"},"packages":[],"prev":{"headline":"Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family Improper Access Control Vulnerability","id":"CVE-2020-3418"},"products":["Cisco WebEx Meetings Server"],"published":"2020-11-18","related":[{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12367","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-0589","kev_date_added":null,"published":"2015-02-07"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Cisco WebEx Meetings Server 2.6","id":"CVE-2017-3794","kev_date_added":null,"published":"2017-01-26"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2016-1448","kev_date_added":null,"published":"2016-07-17"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2016-1446","kev_date_added":null,"published":"2016-07-15"},{"cvss_score":8.6,"headline":"Denial of service in Cisco WebEx Meetings Server","id":"CVE-2017-12293","kev_date_added":null,"published":"2017-10-19"},{"cvss_score":8.1,"headline":"Auth bypass in Cisco WebEx Meetings Server","id":"CVE-2018-0110","kev_date_added":null,"published":"2018-01-18"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"Unauthenticated attackers can join Webex meetings invisibly with full access if they possess valid join credentials, bypassing participant visibility controls.","url":"https://insights.sbomify.com/CVE-2020-3419/"}
