Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-5063 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 5.5.34\n- org.apache.tomcat:tomcat (Maven): affected from 5.5.0; fixed in 5.5.34\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.33\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.33\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.12\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.12\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-2011-5063/ (Markdown: https://insights.sbomify.com/CVE-2011-5063/index.md)","id":"CVE-2011-5063","markdown":"https://insights.sbomify.com/CVE-2011-5063/index.md","name":"CVE-2011-5063","record":{"aliases":["GHSA-hffm-fqv4-w27r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"low_privilege","summary":"Remote attackers can bypass access restrictions in Apache Tomcat by exploiting unchecked realm values in HTTP Digest Authentication when weaker protection spaces are available.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not check realm values, which might allow remote attackers to bypass intended access restrictions by leveraging the availability of a protection space with weaker authentication or authorization requirements, a different vulnerability than CVE-2011-1184.","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":"Improper Authentication in Apache Tomcat","id":"CVE-2011-5063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:tomcat","products":["apache:tomcat"],"type":"auth_bypass","year":"2011"},"n_packages":6,"n_references":22,"next":{"headline":"Use of Hard-coded Cryptographic Key in Apache Tomcat","id":"CVE-2011-5064"},"packages":[{"ecosystem":"Maven","fixed":["5.5.34"],"introduced":["5.5.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-hffm-fqv4-w27r"},{"ecosystem":"Maven","fixed":["5.5.34"],"introduced":["5.5.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-hffm-fqv4-w27r"},{"ecosystem":"Maven","fixed":["6.0.33"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-hffm-fqv4-w27r"},{"ecosystem":"Maven","fixed":["6.0.33"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-hffm-fqv4-w27r"},{"ecosystem":"Maven","fixed":["7.0.12"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-hffm-fqv4-w27r"},{"ecosystem":"Maven","fixed":["7.0.12"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-hffm-fqv4-w27r"}],"prev":{"headline":"Improper Authentication in Apache Tomcat","id":"CVE-2011-5062"},"products":["n/a"],"published":"2012-01-14","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 -
