An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-34415 and fix it if it is affected.\n\nWhat it is: CVE-2021-34415 is a high-severity denial of service vulnerability in Zoom On-Premise Meeting Connector Controller, published on 27 Sep 2021. 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-2021-34415 in the wild and no public exploit code.\n\nAffected product: Zoom On-Premise Meeting Connector Controller. 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-2021-34415/ (Markdown: https://insights.sbomify.com/CVE-2021-34415/index.md)","id":"CVE-2021-34415","markdown":"https://insights.sbomify.com/CVE-2021-34415/index.md","name":"CVE-2021-34415","record":{"aliases":["GHSA-736v-pj2q-r8qr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zoom Meeting Connector","requires_auth":"none","summary":"Attackers can crash the Zoom On-Premise Meeting Connector Controller by sending packets with unverified count fields, causing resource exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zoom","cpe":[{"product":"meeting_connector","vendor":"zoom"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The Zone Controller service in the Zoom On-Premise Meeting Connector Controller before version 4.6.358.20210205 does not verify the cnt field sent in incoming network packets, which leads to exhaustion of resources and system crash.","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":"Denial of service in Zoom On-Premise Meeting Connector Controller","id":"CVE-2021-34415","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Zoom On-Premise Meeting Connector Controller, Zoom On-Premise Meeting Connector MMR, Zoom On-Premise Recording Connector, Zoom On-Premise Virtual Room Connector, Zoom On-Premise Virtual Room Connector Load Balancer","id":"CVE-2021-34416"},"packages":[],"prev":{"headline":"Command injection in Zoom on-premise Meeting Connector Controller, Zoom on-premise Meeting Connector MMR, Zoom on-premise Recording Connector, Zoom on-premise Virtual Room Connector, Zoom on-premise Virtual Room Connector Load Balancer","id":"CVE-2021-34414"},"products":["Zoom On-Premise Meeting Connector Controller"],"published":"2021-09-27","related":[{"cvss_score":9.8,"headline":"Command injection in Zoom On-Premise Meeting Connector Controller, Zoom On-Premise Meeting Connector MMR, Zoom On-Premise Recording Connector, Zoom On-Premise Virtual Room Connector, Zoom On-Premise Virtual Room Connector Load Balancer","id":"CVE-2021-34416","kev_date_added":null,"published":"2021-09-27"},{"cvss_score":7.5,"headline":"Zoom On-Premise Deployments: Stack Buffer Overflow in Meeting Connector","id":"CVE-2022-28750","kev_date_added":null,"published":"2022-08-11"},{"cvss_score":7.2,"headline":"Command injection in Zoom on-premise Meeting Connector Controller, Zoom on-premise Meeting Connector MMR, Zoom on-premise Recording Connector, Zoom on-premise Virtual Room Connector, Zoom on-premise Virtual Room Connector Load Balancer","id":"CVE-2021-34414","kev_date_added":null,"published":"2021-09-27"},{"cvss_score":7.1,"headline":"Zoom On-Premise Deployments: Improper Access Control Vulnerability","id":"CVE-2022-28753","kev_date_added":null,"published":"2022-08-11"},{"cvss_score":7.1,"headline":"Zoom On-Premise Deployments: Improper Access Control Vulnerability","id":"CVE-2022-28754","kev_date_added":null,"published":"2022-08-11"}],"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":"Attackers can crash the Zoom On-Premise Meeting Connector Controller by sending packets with unverified count fields, causing resource exhaustion.","url":"https://insights.sbomify.com/CVE-2021-34415/"}
