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-2020-8631 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2020-8631/ (Markdown: https://insights.sbomify.com/CVE-2020-8631/index.md)","id":"CVE-2020-8631","markdown":"https://insights.sbomify.com/CVE-2020-8631/index.md","name":"CVE-2020-8631","record":{"aliases":["DEBIAN-CVE-2020-8631","GHSA-2r47-hhff-7qcp","UBUNTU-CVE-2020-8631"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"cloud-init utility","requires_auth":"low_privilege","summary":"Attackers can predict random passwords generated by cloud-init due to weak randomness, potentially leading to unauthorized access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cloud-init","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Weak cryptography in n/a","id":"CVE-2020-8631","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","opensuse:leap"],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2020-8632"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-8630"},"products":["n/a"],"published":"2020-02-05","related":[{"cvss_score":8.8,"headline":"Hardcoded credentials in cloud-init","id":"CVE-2024-6174","kev_date_added":null,"published":"2025-06-26"},{"cvss_score":8.8,"headline":"Privilege escalation in cloud-init","id":"CVE-2012-6639","kev_date_added":null,"published":"2019-11-25"},{"cvss_score":5.9,"headline":"Privilege escalation in cloud-init","id":"CVE-2024-11584","kev_date_added":null,"published":"2025-06-26"},{"cvss_score":5.5,"headline":"sensitive data exposure in cloud-init logs","id":"CVE-2023-1786","kev_date_added":null,"published":"2023-04-26"},{"cvss_score":5.5,"headline":"sensitive data exposure in cloud-init logs","id":"CVE-2021-3429","kev_date_added":null,"published":"2023-04-19"},{"cvss_score":5.5,"headline":"sensitive data exposure in cloud-init logs","id":"CVE-2022-2084","kev_date_added":null,"published":"2023-04-19"}],"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 predict random passwords generated by cloud-init due to weak randomness, potentially leading to unauthorized access.","url":"https://insights.sbomify.com/CVE-2020-8631/"}
