An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-22942 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- actionpack (RubyGems): affected from 6.0.0; fixed in 6.0.4.1\n- actionpack (RubyGems): affected from 6.0.0; fixed in 6.0.4.1\n- actionpack (RubyGems): affected from 6.1.0; fixed in 6.1.4.1\n- actionpack (RubyGems): affected from 6.1.0; fixed in 6.1.4.1\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-2021-22942/ (Markdown: https://insights.sbomify.com/CVE-2021-22942/index.md)","id":"CVE-2021-22942","markdown":"https://insights.sbomify.com/CVE-2021-22942/index.md","name":"CVE-2021-22942","record":{"aliases":["DEBIAN-CVE-2021-22942","GHSA-2rqw-v265-jf8c","UBUNTU-CVE-2021-22942"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby on Rails","requires_auth":"none","summary":"Attackers can redirect users to malicious sites via Host Authorization middleware in Action Pack, requiring an upgrade to mitigate.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"rails","vendor":"rubyonrails"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A possible open redirect vulnerability in the Host Authorization middleware in Action Pack \u003e= 6.0.0 that could allow attackers to redirect users to a malicious website.","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":"Open Redirect in ActionPack","id":"CVE-2021-22942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"rubyonrails:rails","products":["rubyonrails:rails"],"type":"open_redirect","year":"2021"},"n_packages":4,"n_references":4,"next":{"headline":"A vulnerability found in UniFi Protect application V1.18.1 and earlier permits a malicious actor who has already gained access to a network","id":"CVE-2021-22943"},"packages":[{"ecosystem":"RubyGems","fixed":["6.0.4.1"],"introduced":["6.0.0"],"last_affected":[],"package":"actionpack","purl":null,"source":"GHSA-2rqw-v265-jf8c"},{"ecosystem":"RubyGems","fixed":["6.0.4.1"],"introduced":["6.0.0"],"last_affected":[],"package":"actionpack","purl":"pkg:gem/actionpack","source":"GHSA-2rqw-v265-jf8c"},{"ecosystem":"RubyGems","fixed":["6.1.4.1"],"introduced":["6.1.0"],"last_affected":[],"package":"actionpack","purl":null,"source":"GHSA-2rqw-v265-jf8c"},{"ecosystem":"RubyGems","fixed":["6.1.4.1"],"introduced":["6.1.0"],"last_affected":[],"package":"actionpack","purl":"pkg:gem/actionpack","source":"GHSA-2rqw-v265-jf8c"}],"prev":{"headline":"Citrix ShareFile Improper Access Control","id":"CVE-2021-22941"},"products":["https://github.com/rails/rails"],"published":"2021-10-18","related":[{"cvss_score":10,"headline":"Active Record contains deserialization of arbitrary YAML","id":"CVE-2013-0277","kev_date_added":null,"published":"2013-02-13"},{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17916","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17917","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8,"headline":"Rails Active Storage has possible Path Traversal in DiskService","id":"CVE-2026-33195","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":7.5,"headline":"Rails possible ReDoS vulnerability in Accept header parsing in Action Dispatch","id":"CVE-2024-26142","kev_date_added":null,"published":"2024-02-27"},{"cvss_score":7.5,"headline":"ReDoS based DoS vulnerability in Action Dispatch","id":"CVE-2023-22792","kev_date_added":null,"published":"2023-02-09"},{"cvss_score":7.5,"headline":"Denial of Service in Action Dispatch","id":"CVE-2021-22902","kev_date_added":null,"published":"2021-06-11"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can redirect users to malicious sites via Host Authorization middleware in Action Pack, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2021-22942/"}
