It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-20215 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-2025-20215/ (Markdown: https://insights.sbomify.com/CVE-2025-20215/index.md)","id":"CVE-2025-20215","markdown":"https://insights.sbomify.com/CVE-2025-20215/index.md","name":"CVE-2025-20215","record":{"aliases":["GHSA-7pj3-g359-9mw7"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Webex Meetings","requires_auth":"none","summary":"An attacker on a local network could bypass certificate validation to join a meeting as another user, requiring Cisco Webex Meetings updates.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability in the meeting-join functionality of Cisco Webex Meetings could have allowed an unauthenticated, network-proximate attacker to complete a meeting-join process in place of an intended targeted user, provided the requisite conditions were satisfied. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.\r\n\r\nThis vulnerability existed due to client certificate validation issues. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by monitoring local wireless or adjacent networks for client-join requests and attempting to interrupt and complete the meeting-join flow as another user who was currently joining a meeting. To successfully exploit the vulnerability, an attacker would need the capability to position themselves in a local wireless or adjacent network, to monitor and intercept the targeted network traffic flows, and to satisfy timing requirements in order to interrupt the meeting-join flow and exploit the vulnerability. A successful exploit could have allowed the attacker to join the meeting as another user. However, the Cisco Product Security Incident Response Team (PSIRT) is not aware of any malicious use of the vulnerability that is described in this advisory.","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 Meeting Client Join Certificate Validation Vulnerability","id":"CVE-2025-20215","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Catalyst SD-WAN Manager Reflected HTML Injection Vulnerability","id":"CVE-2025-20216"},"packages":[],"prev":{"headline":"Missing authorization in Cisco IOS XE Software","id":"CVE-2025-20214"},"products":["Cisco Webex Meetings"],"published":"2025-08-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2025-08-06","vendors":["Cisco"]},"summary":"An attacker on a local network could bypass certificate validation to join a meeting as another user, requiring Cisco Webex Meetings updates.","url":"https://insights.sbomify.com/CVE-2025-20215/"}
