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-2009-2422 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rails (RubyGems): affected all versions; fixed in 2.3.3\n- rails (RubyGems): affected all versions; fixed in 2.3.3\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-2009-2422/ (Markdown: https://insights.sbomify.com/CVE-2009-2422/index.md)","id":"CVE-2009-2422","markdown":"https://insights.sbomify.com/CVE-2009-2422/index.md","name":"CVE-2009-2422","record":{"aliases":["DEBIAN-CVE-2009-2422","GHSA-rxq3-gm4p-5fj4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Ruby on Rails","requires_auth":"none","summary":"Attackers can bypass authentication in Ruby on Rails applications using the vulnerable example digest authentication code by sending an invalid username without a password.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"mac_os_x_server","vendor":"apple"},{"product":"ruby_on_rails","vendor":"rubyonrails"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The example code for the digest authentication functionality (http_authentication.rb) in Ruby on Rails before 2.3.3 defines an authenticate_or_request_with_http_digest block that returns nil instead of false when the user does not exist, which allows context-dependent attackers to bypass authentication for applications that are derived from this example by sending an invalid username without a password.","ecosystems":["RubyGems"],"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":"rails vulnerable to improper authentication","id":"CVE-2009-2422","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"apple:mac_os_x","products":["apple:mac_os_x","apple:mac_os_x_server"],"type":"auth_bypass","year":"2009"},"n_packages":2,"n_references":8,"next":{"headline":"SQL injection in n/a","id":"CVE-2009-2423"},"packages":[{"ecosystem":"RubyGems","fixed":["2.3.3"],"introduced":["0"],"last_affected":[],"package":"rails","purl":null,"source":"GHSA-rxq3-gm4p-5fj4"},{"ecosystem":"RubyGems","fixed":["2.3.3"],"introduced":["0"],"last_affected":[],"package":"rails","purl":"pkg:gem/rails","source":"GHSA-rxq3-gm4p-5fj4"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2009-2421"},"products":["n/a"],"published":"2009-07-10","related":[{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-7169","kev_date_added":"2022-01-28","published":"2014-09-25"},{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-6271","kev_date_added":"2022-01-28","published":"2014-09-24"},{"cvss_score":9.8,"headline":"PHP-CGI Query String Parameter","id":"CVE-2012-1823","kev_date_added":"2022-03-25","published":"2012-05-11"},{"cvss_score":7.8,"headline":"Apple macOS Unspecified","id":"CVE-2021-30713","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":7.8,"headline":"Apple macOS Use-After-Free","id":"CVE-2019-8526","kev_date_added":"2023-04-17","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple OS X Authentication Bypass","id":"CVE-2015-1130","kev_date_added":"2022-02-10","published":"2015-04-10"},{"cvss_score":5.5,"headline":"Apple macOS Out-of-Bounds Read","id":"CVE-2022-22674","kev_date_added":"2022-04-04","published":"2022-05-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"Attackers can bypass authentication in Ruby on Rails applications using the vulnerable example digest authentication code by sending an invalid username without a password.","url":"https://insights.sbomify.com/CVE-2009-2422/"}
