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-2020-1887 in the wild and no public exploit code.\n\nAffected product: Facebook Osquery. 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-2020-1887/ (Markdown: https://insights.sbomify.com/CVE-2020-1887/index.md)","id":"CVE-2020-1887","markdown":"https://insights.sbomify.com/CVE-2020-1887/index.md","name":"CVE-2020-1887","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"osquery endpoint agent","requires_auth":"none","summary":"Attackers can intercept osquery traffic via MITM due to improper TLS SNI validation when no root chain of trust is configured.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"osquery","vendor":"linuxfoundation"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"Incorrect validation of the TLS SNI hostname in osquery versions after 2.9.0 and before 4.2.0 could allow an attacker to MITM osquery traffic in the absence of a configured root chain of trust.","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":"Weak cryptography in Osquery","id":"CVE-2020-1887","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in HHVM","id":"CVE-2020-1888"},"packages":[],"prev":{"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2020-1886"},"products":["Osquery"],"published":"2020-03-12","related":[{"cvss_score":8.1,"headline":"Path traversal in osquery","id":"CVE-2019-3567","kev_date_added":null,"published":"2019-06-03"},{"cvss_score":7.8,"headline":"Security feature bypass in osquery","id":"CVE-2018-6336","kev_date_added":null,"published":"2018-12-31"},{"cvss_score":5.3,"headline":"osquery susceptible to DLL search order hijacking of zlib1.dll","id":"CVE-2020-11081","kev_date_added":null,"published":"2020-07-10"},{"cvss_score":5.2,"headline":"sqlite ATTACH allows some filesystem access","id":"CVE-2020-26273","kev_date_added":null,"published":"2020-12-16"}],"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":["Facebook"]},"summary":"Attackers can intercept osquery traffic via MITM due to improper TLS SNI validation when no root chain of trust is configured.","url":"https://insights.sbomify.com/CVE-2020-1887/"}
