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-2019-15987 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings Online. 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-2019-15987/ (Markdown: https://insights.sbomify.com/CVE-2019-15987/index.md)","id":"CVE-2019-15987","markdown":"https://insights.sbomify.com/CVE-2019-15987/index.md","name":"CVE-2019-15987","record":{"aliases":["GHSA-99jc-7925-7fc9"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco WebEx Centers","requires_auth":"none","summary":"Unauthenticated attackers can enumerate valid usernames and retrieve real names due to missing CAPTCHA protection in Cisco WebEx web interfaces.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_event_center","vendor":"cisco"},{"product":"webex_meeting_center","vendor":"cisco"},{"product":"webex_meetings_online","vendor":"cisco"},{"product":"webex_meetings_server","vendor":"cisco"},{"product":"webex_support_center","vendor":"cisco"},{"product":"webex_training_center","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A vulnerability in web interface of the Cisco Webex Event Center, Cisco Webex Meeting Center, Cisco Webex Support Center, and Cisco Webex Training Center could allow an unauthenticated, remote attacker to guess account usernames.
