Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3542 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings. 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-2020-3542/ (Markdown: https://insights.sbomify.com/CVE-2020-3542/index.md)","id":"CVE-2020-3542","markdown":"https://insights.sbomify.com/CVE-2020-3542/index.md","name":"CVE-2020-3542","record":{"aliases":["GHSA-f5m9-r5hc-4gww"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex Training","requires_auth":"low_privilege","summary":"Authenticated attackers can bypass meeting password protection to join private sessions via API manipulation, requiring Cisco Webex Training users to apply vendor patches.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_training","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","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-20","name":"Improper Input Validation"}],"description":"A vulnerability in Cisco Webex Training could allow an authenticated, remote attacker to join a password-protected meeting without providing the meeting password. The vulnerability is due to improper validation of input to API requests that are a part of meeting join flow. An attacker could exploit this vulnerability by sending an API request to the application, which would return a URL that includes a meeting join page that is prepopulated with the meeting username and password. A successful exploit could allow the attacker to join the password-protected meeting. The attacker would be visible in the attendee list of the meeting.","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 Training Unauthorized Meeting Join Vulnerability","id":"CVE-2020-3542","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Memory Leak Vulnerability","id":"CVE-2020-3543"},"packages":[],"prev":{"headline":"Information disclosure in Cisco Webex Meetings","id":"CVE-2020-3541"},"products":["Cisco Webex Meetings"],"published":"2020-09-04","related":[],"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":"Authenticated attackers can bypass meeting password protection to join private sessions via API manipulation, requiring Cisco Webex Training users to apply vendor patches.","url":"https://insights.sbomify.com/CVE-2020-3542/"}
