It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-8900 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-2017-8900/ (Markdown: https://insights.sbomify.com/CVE-2017-8900/index.md)","id":"CVE-2017-8900","markdown":"https://insights.sbomify.com/CVE-2017-8900/index.md","name":"CVE-2017-8900","record":{"aliases":["GHSA-2r8v-9m34-p378"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"LightDM display manager","requires_auth":"none","summary":"Physically proximate attackers can bypass AppArmor restrictions via guest sessions to access arbitrary user home directories in Ubuntu systems using LightDM.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lightdm","vendor":"lightdm_project"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[],"description":"LightDM through 1.22.0, when systemd is used in Ubuntu 16.10 and 17.x, allows physically proximate attackers to bypass intended AppArmor restrictions and visit the home directories of arbitrary users by establishing a guest session.","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":"Security feature bypass in n/a","id":"CVE-2017-8900","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2017"},"n_packages":0,"n_references":4,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2017-8903"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2017-8899"},"products":["n/a"],"published":"2017-05-12","related":[{"cvss_score":7.8,"headline":"Privilege escalation in lightdm","id":"CVE-2011-3349","kev_date_added":null,"published":"2019-11-19"},{"cvss_score":5.9,"headline":"Denial of service in n/a","id":"CVE-2015-8316","kev_date_added":null,"published":"2017-09-06"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Physically proximate attackers can bypass AppArmor restrictions via guest sessions to access arbitrary user home directories in Ubuntu systems using LightDM.","url":"https://insights.sbomify.com/CVE-2017-8900/"}
