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-2008-3905 in the wild and no public exploit code.\n\nAffected product: Ruby-Lang Ruby. 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-2008-3905/ (Markdown: https://insights.sbomify.com/CVE-2008-3905/index.md)","id":"CVE-2008-3905","markdown":"https://insights.sbomify.com/CVE-2008-3905/index.md","name":"CVE-2008-3905","record":{"aliases":["GHSA-vwcj-mf69-7rfw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby standard library","requires_auth":"none","summary":"Remote attackers can spoof DNS responses due to predictable transaction IDs and source ports in Ruby's resolv library, bypassing DNS security checks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ruby","vendor":"ruby-lang"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447.","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":"Security feature bypass in n/a","id":"CVE-2008-3905","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ruby-lang:ruby","products":["ruby-lang:ruby"],"type":"security_feature_bypass","year":"2008"},"n_packages":0,"n_references":24,"next":{"headline":"Other in n/a","id":"CVE-2008-3906"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2008-3904"},"products":["n/a"],"published":"2008-09-04","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-4124","kev_date_added":null,"published":"2009-12-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-28738","kev_date_added":null,"published":"2022-05-09"},{"cvss_score":9.8,"headline":"Weak cryptography in OpenSSL extension of Ruby (Git trunk)","id":"CVE-2011-4121","kev_date_added":null,"published":"2019-11-26"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-17790","kev_date_added":null,"published":"2017-12-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11465","kev_date_added":null,"published":"2017-07-19"},{"cvss_score":9.8,"headline":"Memory corruption in Ruby","id":"CVE-2016-2336","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":9.8,"headline":"Code injection in Ruby","id":"CVE-2016-2337","kev_date_added":null,"published":"2017-01-06"}],"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":"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can spoof DNS responses due to predictable transaction IDs and source ports in Ruby's resolv library, bypassing DNS security checks.","url":"https://insights.sbomify.com/CVE-2008-3905/"}
