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-2021-45489 in the wild and no public exploit code.\n\nAffected product: Netbsd Netbsd. 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-2021-45489/ (Markdown: https://insights.sbomify.com/CVE-2021-45489/index.md)","id":"CVE-2021-45489","markdown":"https://insights.sbomify.com/CVE-2021-45489/index.md","name":"CVE-2021-45489","record":{"aliases":["GHSA-rgh6-hjmr-j5fv"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NetBSD OS","requires_auth":"none","summary":"NetBSD uses a weak PRNG for IPv6 Flow Labels, potentially allowing attackers to bypass security controls relying on label unpredictability.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netbsd","vendor":"netbsd"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"In NetBSD through 9.2, the IPv6 Flow Label generation algorithm employs a weak cryptographic PRNG.","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":"Weak cryptography in n/a","id":"CVE-2021-45489","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netbsd:netbsd","products":["netbsd:netbsd"],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2021-45490"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-45488"},"products":["n/a"],"published":"2021-12-25","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2017-1000374","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-1000375","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2017-1000378","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2015-8212","kev_date_added":null,"published":"2017-01-19"},{"cvss_score":9.3,"headline":"Denial of service in n/a","id":"CVE-2008-3584","kev_date_added":null,"published":"2008-09-11"},{"cvss_score":9.3,"headline":"Security feature bypass in n/a","id":"CVE-2008-1335","kev_date_added":null,"published":"2008-03-13"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2016-6253","kev_date_added":null,"published":"2017-01-20"}],"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":"NetBSD uses a weak PRNG for IPv6 Flow Labels, potentially allowing attackers to bypass security controls relying on label unpredictability.","url":"https://insights.sbomify.com/CVE-2021-45489/"}
