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-2021-28133 in the wild and no public exploit code.\n\nAffected product: Zoom Zoom. 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-2021-28133/ (Markdown: https://insights.sbomify.com/CVE-2021-28133/index.md)","id":"CVE-2021-28133","markdown":"https://insights.sbomify.com/CVE-2021-28133/index.md","name":"CVE-2021-28133","record":{"aliases":["GHSA-qj56-qx26-7qr8"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Zoom desktop client","requires_auth":"none","summary":"Attackers can view private screen contents not explicitly shared during Zoom meetings, exposing sensitive data to other participants.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zoom","vendor":"zoom"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Zoom through 5.5.4 sometimes allows attackers to read private information on a participant's screen, even though the participant never attempted to share the private part of their screen. When a user shares a specific application window via the Share Screen functionality, other meeting participants can briefly see contents of other application windows that were explicitly not shared. The contents of these other windows can (for instance) be seen for a short period of time when they overlay the shared window and get into focus. (An attacker can, of course, use a separate screen-recorder application, unsupported by Zoom, to save all such contents for later replays and analysis.) Depending on the unintentionally shared data, this short exposure of screen contents may be a more or less severe security issue.","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":"Information disclosure in n/a","id":"CVE-2021-28133","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zoom:zoom","products":["zoom:zoom"],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":7,"next":{"headline":"Command injection in n/a","id":"CVE-2021-28134"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2021-28132"},"products":["n/a"],"published":"2021-03-18","related":[{"cvss_score":9.8,"headline":"Missing authorization in Zoom","id":"CVE-2018-15715","kev_date_added":null,"published":"2018-11-30"},{"cvss_score":9.6,"headline":"Cross-site scripting in Zoom Desktop Client for Windows","id":"CVE-2023-39216","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":9.3,"headline":"Path traversal in Zoom Desktop Client for Windows","id":"CVE-2023-36534","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-13567","kev_date_added":null,"published":"2019-07-12"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-15048","kev_date_added":null,"published":"2017-12-19"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2017-15049","kev_date_added":null,"published":"2017-12-19"},{"cvss_score":8.5,"headline":"Path traversal in Zoom","id":"CVE-2020-6109","kev_date_added":null,"published":"2020-06-08"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can view private screen contents not explicitly shared during Zoom meetings, exposing sensitive data to other participants.","url":"https://insights.sbomify.com/CVE-2021-28133/"}
