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-2022-30122 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rack (RubyGems): affected from 1.2; fixed in 2.0.9.1\n- rack (RubyGems): affected from 1.2; fixed in 2.0.9.1\n- rack (RubyGems): affected from 2.1; fixed in 2.1.4.1\n- rack (RubyGems): affected from 2.1; fixed in 2.1.4.1\n- rack (RubyGems): affected from 2.2; fixed in 2.2.3.1\n- rack (RubyGems): affected from 2.2; fixed in 2.2.3.1\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-2022-30122/ (Markdown: https://insights.sbomify.com/CVE-2022-30122/index.md)","id":"CVE-2022-30122","markdown":"https://insights.sbomify.com/CVE-2022-30122/index.md","name":"CVE-2022-30122","record":{"aliases":["DEBIAN-CVE-2022-30122","GHSA-hxqx-xwvh-44m2","UBUNTU-CVE-2022-30122"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby web server library","requires_auth":"none","summary":"Attackers can cause a denial of service in Rack by exploiting inefficient multipart parsing, affecting Ruby web applications.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"rack","vendor":"rack_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A possible denial of service vulnerability exists in Rack \u003c2.0.9.1, \u003c2.1.4.1 and \u003c2.2.3.1 in the multipart parsing component of Rack.","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":"Denial of Service Vulnerability in Rack Multipart Parsing","id":"CVE-2022-30122","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"denial_of_service","year":"2022"},"n_packages":6,"n_references":4,"next":{"headline":"Possible shell escape sequence injection vulnerability in Rack","id":"CVE-2022-30123"},"packages":[{"ecosystem":"RubyGems","fixed":["2.0.9.1"],"introduced":["1.2"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-hxqx-xwvh-44m2"},{"ecosystem":"RubyGems","fixed":["2.0.9.1"],"introduced":["1.2"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-hxqx-xwvh-44m2"},{"ecosystem":"RubyGems","fixed":["2.1.4.1"],"introduced":["2.1"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-hxqx-xwvh-44m2"},{"ecosystem":"RubyGems","fixed":["2.1.4.1"],"introduced":["2.1"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-hxqx-xwvh-44m2"},{"ecosystem":"RubyGems","fixed":["2.2.3.1"],"introduced":["2.2"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-hxqx-xwvh-44m2"},{"ecosystem":"RubyGems","fixed":["2.2.3.1"],"introduced":["2.2"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-hxqx-xwvh-44m2"}],"prev":{"headline":"Privilege escalation in Ivanti Endpoint Manager","id":"CVE-2022-30121"},"products":["https://github.com/rack/rack"],"published":"2022-12-05","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in Rack by exploiting inefficient multipart parsing, affecting Ruby web applications.","url":"https://insights.sbomify.com/CVE-2022-30122/"}
