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-2012-0022 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected from 5.5.0; fixed in 5.5.35\n- org.apache.tomcat:tomcat (Maven): affected from 5.5.0; fixed in 5.5.35\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.34\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.34\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.23\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.23\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-2012-0022/ (Markdown: https://insights.sbomify.com/CVE-2012-0022/index.md)","id":"CVE-2012-0022","markdown":"https://insights.sbomify.com/CVE-2012-0022/index.md","name":"CVE-2012-0022","record":{"aliases":["GHSA-8h2q-qm9x-55jc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Remote attackers can cause denial of service via CPU consumption by sending requests with many parameters in Apache Tomcat.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.34, and 7.x before 7.0.23 uses an inefficient approach for handling parameters, which allows remote attackers to cause a denial of service (CPU consumption) via a request that contains many parameters and parameter values, a different vulnerability than CVE-2011-4858.","ecosystems":["Maven"],"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 in Apache Tomcat","id":"CVE-2012-0022","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:tomcat","products":["apache:tomcat"],"type":"denial_of_service","year":"2012"},"n_packages":6,"n_references":35,"next":{"headline":"Use after free in n/a","id":"CVE-2012-0023"},"packages":[{"ecosystem":"Maven","fixed":["5.5.35"],"introduced":["5.5.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-8h2q-qm9x-55jc"},{"ecosystem":"Maven","fixed":["5.5.35"],"introduced":["5.5.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-8h2q-qm9x-55jc"},{"ecosystem":"Maven","fixed":["6.0.34"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-8h2q-qm9x-55jc"},{"ecosystem":"Maven","fixed":["6.0.34"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-8h2q-qm9x-55jc"},{"ecosystem":"Maven","fixed":["7.0.23"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-8h2q-qm9x-55jc"},{"ecosystem":"Maven","fixed":["7.0.23"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-8h2q-qm9x-55jc"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-0021"},"products":["n/a"],"published":"2012-01-19","related":[{"cvss_score":10,"headline":"Apache Tomcat Path Equivalence","id":"CVE-2025-24813","kev_date_added":"2025-04-01","published":"2025-03-10"},{"cvss_score":9.8,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2016-8735","kev_date_added":"2023-05-12","published":"2017-04-06"},{"cvss_score":8.1,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2017-12617","kev_date_added":"2022-03-25","published":"2017-10-03"},{"cvss_score":8.1,"headline":"Apache Tomcat on Windows Remote Code Execution","id":"CVE-2017-12615","kev_date_added":"2022-03-25","published":"2017-09-19"},{"cvss_score":7.5,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","kev_date_added":"2026-08-04","published":"2026-04-09"},{"cvss_score":9.8,"headline":"Apache Tomcat: HTTP/2 no-authority bypass of strict SNI validation - CVE-2026-32990 fix incomplete","id":"CVE-2026-65637","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.8,"headline":"Apache Tomcat: Limited replay attack possible with DIGEST authentication","id":"CVE-2026-65905","kev_date_added":null,"published":"2026-08-25"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via CPU consumption by sending requests with many parameters in Apache Tomcat.","url":"https://insights.sbomify.com/CVE-2012-0022/"}
