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-2020-27611 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-27611/ (Markdown: https://insights.sbomify.com/CVE-2020-27611/index.md)","id":"CVE-2020-27611","markdown":"https://insights.sbomify.com/CVE-2020-27611/index.md","name":"CVE-2020-27611","record":{"aliases":["GHSA-2pxm-qg5m-jmf9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BigBlueButton web conferencing","requires_auth":"none","summary":"BigBlueButton uses third-party STUN/TURN resources, potentially allowing attackers to access unintended internal endpoints via Server-Side Request Forgery.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bigbluebutton","vendor":"bigbluebutton"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"BigBlueButton through 2.2.28 uses STUN/TURN resources from a third party, which may represent an unintended endpoint.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Server-side request forgery in n/a","id":"CVE-2020-27611","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-27612"},"packages":[],"prev":{"headline":"Misconfiguration in n/a","id":"CVE-2020-27610"},"products":["n/a"],"published":"2020-10-21","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2020-27602","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-27605","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-12443","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":8.4,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27613","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":8.1,"headline":"Cross-site Scripting (XSS) - Generic in bigbluebutton/bigbluebutton","id":"CVE-2021-4143","kev_date_added":null,"published":"2022-01-19"},{"cvss_score":7.5,"headline":"BigBlueButton vulnerable to DoS via PollSubmitVote GraphQL mutation","id":"CVE-2025-61601","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":7.5,"headline":"BigBlueButton vulnerable to Chat DoS via invalid reactionEmojiId","id":"CVE-2025-61602","kev_date_added":null,"published":"2025-10-09"}],"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":"BigBlueButton uses third-party STUN/TURN resources, potentially allowing attackers to access unintended internal endpoints via Server-Side Request Forgery.","url":"https://insights.sbomify.com/CVE-2020-27611/"}
