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-2012-6109 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rack (RubyGems): affected all versions; fixed in 1.1.4\n- rack (RubyGems): affected all versions; fixed in 1.1.4\n- rack (RubyGems): affected from 1.2.0; fixed in 1.2.6\n- rack (RubyGems): affected from 1.2.0; fixed in 1.2.6\n- rack (RubyGems): affected from 1.3.0; fixed in 1.3.7\n- rack (RubyGems): affected from 1.3.0; fixed in 1.3.7\n- rack (RubyGems): affected from 1.4.0; fixed in 1.4.2\n- rack (RubyGems): affected from 1.4.0; fixed in 1.4.2\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-2012-6109/ (Markdown: https://insights.sbomify.com/CVE-2012-6109/index.md)","id":"CVE-2012-6109","markdown":"https://insights.sbomify.com/CVE-2012-6109/index.md","name":"CVE-2012-6109","record":{"aliases":["DEBIAN-CVE-2012-6109","GHSA-h77x-m5q8-c29h","UBUNTU-CVE-2012-6109"],"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":"Remote attackers can cause a denial of service via an infinite loop triggered by a crafted Content-Disposition header in the Rack library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"rack","vendor":"rack_project"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"lib/rack/multipart.rb in Rack before 1.1.4, 1.2.x before 1.2.6, 1.3.x before 1.3.7, and 1.4.x before 1.4.2 uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.","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":"Rack vulnerable to REDoS","id":"CVE-2012-6109","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"denial_of_service","year":"2012"},"n_packages":8,"n_references":7,"next":{"headline":"Missing authorization in n/a","id":"CVE-2012-6110"},"packages":[{"ecosystem":"RubyGems","fixed":["1.1.4"],"introduced":["0"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.1.4"],"introduced":["0"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.2.6"],"introduced":["1.2.0"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.2.6"],"introduced":["1.2.0"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.3.7"],"introduced":["1.3.0"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.3.7"],"introduced":["1.3.0"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.4.2"],"introduced":["1.4.0"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-h77x-m5q8-c29h"},{"ecosystem":"RubyGems","fixed":["1.4.2"],"introduced":["1.4.0"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-h77x-m5q8-c29h"}],"prev":{"headline":"Misconfiguration in n/a","id":"CVE-2012-6108"},"products":["n/a"],"published":"2013-03-01","related":[{"cvss_score":7.5,"headline":"Rack vulnerable to Denial of Service","id":"CVE-2018-16470","kev_date_added":null,"published":"2018-11-13"},{"cvss_score":5.1,"headline":"Rack arbitrary code execution via timing attack","id":"CVE-2013-0263","kev_date_added":null,"published":"2013-02-08"},{"cvss_score":5,"headline":"Rack rubygems receiving excessively long lines triggers out-of-memory error","id":"CVE-2013-0183","kev_date_added":null,"published":"2013-03-01"},{"cvss_score":5,"headline":"Rack Gem Subject to Denial of Service via Hash Collisions","id":"CVE-2011-5036","kev_date_added":null,"published":"2011-12-30"},{"cvss_score":4.3,"headline":"Rack vulnerable to Denial of Service","id":"CVE-2013-0184","kev_date_added":null,"published":"2013-03-01"},{"cvss_score":4.3,"headline":"Rack Vulnerable to Path Traversal","id":"CVE-2013-0262","kev_date_added":null,"published":"2013-02-08"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via an infinite loop triggered by a crafted Content-Disposition header in the Rack library.","url":"https://insights.sbomify.com/CVE-2012-6109/"}
